1 · First things first
Three steps, and the app starts genuinely working for you. The second one is the one almost everybody skips, and it's the one that matters most.
- Create your pet. A name and a species are enough to start; photo, breed, date of birth and weight can come later.
- Declare their chronic conditions, from the pet profile. This isn't paperwork: it's how the app works out what to show you — with kidney disease you get SC fluids and blood values, with epilepsy you get the seizure timer.
- Add the medications they're on, with the real times. From that moment the reminders arm themselves, without you setting anything up.
If somebody shares the care with you — a partner, a grown-up child, whoever looks after them when you're away — invite them now, from Invite family. They'll see the same pet and be able to mark doses: that's how you avoid giving two. How it works.
2 · How the app is laid out
There are five tabs along the bottom of the screen. They are the app's five drawers: nearly everything you're looking for lives in one of them.
The Home screen, top to bottom
- The pet selector. If you have more than one, this is where you say who you're talking about: everything below changes to match. Tapping the name or the photo opens the profile.
- The Emergency Card, the panel right below it. Chapter 13.
- Today for… with the day's doses, and a Next 7 days tab for looking ahead.
- The quick actions, the grid of tiles. Chapter 4.
- Recent activity: what was recorded, by you or by a family member. "You gave Metacam", "Marco skipped the insulin", "You logged a symptom: limping". This is where you see what the other person did while you weren't there.
One thing to know about the Home screen. There are two words at the top, Health and Food. They are not a heading: they are a switch, and they change everything below them.
On Health you get today's doses, the quick actions and recent activity. On Food you get meals and water. If you're hunting for the food diary and can't find it, nine times out of ten you're still on the Health side.
3 · The pet profile
Pet profile opens when you tap the name or the photo at the top of the Home screen. It's the most important screen after the Home, and it's the one almost nobody opens — even though it's where you decide what the app will show you.
What's inside, from the top
- Weight. The current figure and how it has moved. You add a reading with + Log weight: it's the first thing a vet looks at, and two readings are enough for the app to start showing you the direction.
- Veterinarian. Name, phone and address. The number becomes callable with one tap.
- Chronic conditions. As many as you need, and if the one you're after isn't in the list you type it in under Other conditions. For each one you can say since when. This is what switches the right features on by itself.
- Monitoring tools. The switches, one by one: the ones you turn on appear in the Home screen's quick actions. Chapter 10.
- Allergies and Important notes. Free text: this is where you write down the things you'd say out loud to whoever is looking after them instead of you.
- Health data. A summary for this pet — vaccines, medications, visits, symptoms, documents — with the latest entries in view and View all to open the full list.
- Family, to manage who else can see this pet. Chapter 14.
- At the bottom, Delete pet: removes the pet and all their records — vaccines, visits, symptoms, documents, medications. There is no going back.
The pencil icon at the top opens Edit pet: photo, name, species, breed, date of birth, weight and the vet's details.
What you write here is the Emergency Card. Vet, conditions, allergies and notes are the same fields that show up on the card you hold out in a clinic (chapter 13). Filling them in isn't about being tidy: it's for that moment.
4 · Quick actions
Scroll down the Home screen, below today's doses, and you'll find a grid of tiles: shortcuts to the things you do most. They always apply to the pet selected at the top — if you have more than one, check the name before you tap.
Below those, if you've switched them on, come the tiles for the nine monitoring tools: Glucose, Seizure timer, Temperature, Breathing rate, SC fluids, Quality of life, Lumps, Blood values, Stools.
How the tools get switched on. There are two ways.
The first: More tools, where you turn them on and off by hand, one at a time.
The second, and the easier one: open the pet profile and declare the chronic conditions they have. The app switches on the ones that illness needs.
If you hit a padlock. Recording your data is always free, and it stays free: what you pay for is the trends over time — the charts, the blood values, the Insights — and how many pets, medications, documents and reports you can keep at once. The full table is in chapter 15.
A padlock never hides what you've already written. If you decide not to subscribe, your data stays yours and you can always export it.
5 · Medications and doses
This is the part of the app you'll use every day. It's worth spending five minutes setting a course up properly: everything else — reminders, the report, adherence — grows out of it.
Adding a medication
From Medications → Add medication. The fields, in order:
- Name and Form — pill, liquid, injection, topical, other.
- Dose (optional) with its unit: the prescribed one. You'll use it as the reference when you log the doses you actually give.
- Frequency. Once, twice or three times a day, every X hours, custom, or as needed.
- Times. With the fixed frequencies the app lays out the slots and you tap to correct them. With "every X hours" you only set the first dose and the app works out the rest. With "as needed" there is no schedule at all: you log a dose when you give one.
- Start date, then either ongoing therapy (no end, until you stop it yourself) or a duration in days — handy for a ten-day antibiotic, which then closes itself.
- For condition (optional). Linking a medication to a condition is what makes the report show which drug treats what.
- Doses per pack (optional). Fill it in and the app keeps count of what's left and warns you when you're down to two. When you open the new box you tap Refill pack and the counter starts again.
- Track injection site (injections only, Pro plan). At every dose it asks "where did you inject?" — left, right, other — so rotating sites becomes something that actually happens rather than something you're supposed to do.
When you save, if you haven't granted them yet, the app asks for notification permission. Say yes: without it the reminders can't fire.
Logging a dose
On the Home screen, under Today for…, you get the whole day's doses in time order. Each behaves differently depending on where you are in the day:
- Doses that are due or overdue have a Mark as given button.
- Doses that are still to come show a padlock: that's not a fault, it's the app telling you that hour hasn't arrived. If you need to give it early you can still tap it.
- Doses already given stay marked, with the time. If you got it wrong, you undo it from the same row.
When you log one you can pick the status — Given, Skipped or Missed — change the dose actually given if it was different from the prescribed one that day, and correct the time if you're logging it late (Now or a time you type in).
Skipped and Missed are not the same thing, which is why they're two separate options. Skipped is a decision — the vomiting, the vet telling you to hold off. Missed is an oversight. In the report and in the Insights those two tell different stories, and telling them apart costs one tap.
Ending a course
Two different routes, and it's worth not mixing them up:
- End therapy moves the medication into the history. The reminders stop, but the dose log stays and still feeds the reports. This is almost always the right choice.
- Delete medication erases the medication and every dose you logged, for good. It's only for something you added by mistake.
Ended courses no longer count against your plan's limit.
6 · Symptoms
This is the diary of what you notice. Your vet sees the animal for twenty minutes every three months; you see them every day. This is the part nobody else can write for you.
Logging one
- Add symptom, from the Home screen or from the Health tab.
- Pick the symptom. They're grouped into eight categories — digestive, general, skin, respiratory, mobility, behaviour, head, urinary — and there's a search box. If what you want isn't there, you add it as a custom symptom and it stays available next time.
- Give it an intensity, from very mild to critical.
- Add more symptoms if they happened together: they save in one go, with the same date and time.
- When: now, or the real date and time if you're writing it up later.
The two fields that make the difference
In what circumstances. Optional, and worth more than all the rest. After getting down off the sofa. Lying down at night. Water rather than food. White foam rather than food. Two regurgitations in different circumstances have different causes, and this is the one line that lets a vet tell them apart.
The photo. A patch of redness, a swelling, a limp that words describe badly. You can take it there and then or pick it from your gallery. It saves your vet the question "what exactly did it look like?", which two weeks later nobody can answer.
What you get back
- Timeline: every episode in order, with a summary of the last 7 days — how many events, the average intensity, and whether the direction is improving, stable or getting worse.
- Charts (Plus), over 30 or 90 days: episodes per week, the most frequent symptoms, a day-by-day intensity calendar, and the split by severity. Above the charts the app also counts the symptom-free days, which is often the number that really tells you whether a treatment is working.
7 · Food and water
You get here by flipping the Home screen to the Food side. For a lot of illnesses — megaesophagus, EPI, kidney disease, diabetes — what they eat and how they eat it is half the treatment.
A meal or a treat
Beyond what and how much, these are the fields that matter for a sick animal:
- Consistency: slurry, meatball, soaked kibble, pureed canned — or in your own words.
- How it was given: by spoon, in the chair, held upright. For a megaesophagus dog that's the main clinical detail.
- Enzymes in this meal: how much, in this bowl. They live here rather than with the medications because they belong to the meal — that's how you follow pancreatic insufficiency.
- How much did they eat: all, half, none. Three taps that become the appetite trend in the report.
Water
Log water doesn't ask for millilitres: it asks for normal, less than usual or more than usual. That's deliberate — excessive thirst is a signal that counts in kidney disease and diabetes, and spotting it takes consistency, not precision.
Meal times
Under Meal reminders you set the times you feed them. The alert goes to the whole family, not just to you: that's how you avoid a second dinner.
In the history, tap an entry to edit it and press and hold to delete it.
8 · Weight, vaccines, visits, documents
Four separate registers that together make the medical file. Each one answers a question you get asked at a reception desk sooner or later.
Weight
Logged from the pet profile with + Log weight. The history shows the current figure, the change and the chart. Two readings are enough to see the direction, and in the report weight is the first thing a vet looks at.
Vaccines
For each one: the name (with suggestions for dogs or cats), the date given and the validity — 6 months, 1, 2 or 3 years, no expiry, or a number of months you type in. From that the app works out the next due date, puts it at the top of the screen and warns you 30, 7 and 1 day before, at 9 in the morning.
Vet visits
Date, reason, the vet's name, the cost, the outcome and notes (what happened, what was prescribed) and a follow-up date. The follow-up doesn't just sit there: it becomes an appointment in the calendar, so "see you in three months" doesn't get lost.
The most recent visit with a follow-up shows at the top as the next visit. And the cost, over the years, answers a very practical question: what is this illness actually costing me.
Documents
Reports, test results, prescriptions, certificates, bills. You add them as a PDF, a photo from your gallery or by taking a picture on the spot, and they file into six categories: vaccine, test, prescription, visit, bill, other.
- There's a search by name, and a filter by category.
- You can give a document an expiry date: anything about to expire moves into an Expiring soon section at the top, with the days left. That's for certificates and passports, which always expire at the wrong moment.
- Share sends the file by email or message without you having to go hunting for it in your gallery.
9 · Calendar and reminders
The calendar
It shows a month at a time, and days with something scheduled carry a dot in the pet's colour. Below the grid is the detail for whichever day you pick, and at the top two sections: Overdue and Upcoming. The red number on the Home screen tile counts the overdue ones.
Everything lands in here: vaccines falling due, visits, follow-ups, the start and end of a course, medication doses, meals, documents about to expire, the reminders you create — and their birthday. With more than one pet you can see them all together or one at a time.
Reminders
There are two kinds, and they behave differently.
Which alerts you can get
In More → Manage notifications they're all listed, grouped by type. Each one switches on and off on its own: if one annoys you, turn off that one and keep the rest.
| Alert | When it arrives |
|---|---|
| Dose reminders | at every scheduled time of the course |
| Missed dose alerts | after 60 minutes, if you haven't logged it |
| Refill reminders | when two doses or fewer are left |
| Vaccine expiry | 30, 7 and 1 day before, at 9:00 |
| Meal reminders | at the meal times you set |
| Family activity | when a family member gives a medication |
These preferences apply to this phone only. If you use Sereno on another device you set them there separately — and that's on purpose: whoever has the animal during the day may want different alerts from whoever has them at night.
If notifications aren't arriving, before assuming something is broken check these three things, in this order:
- Permission. The app has to be allowed to send notifications: check it in your phone's settings, under the app. If they're blocked, Sereno says so and opens the right settings page for you.
- Battery saving. On a lot of Android phones the system puts apps you use rarely to sleep, and the notifications never fire. Find the battery optimisation setting and take Sereno out of it.
- The categories. In Manage notifications you can switch off individual alert types: check that the one you're waiting for isn't switched off there.
10 · The monitoring tools
Nine tools that stay switched off until they're needed, and appear in the quick actions once you turn them on. You'll never see all of them at once: the app shows you the ones that have something to do with the illness you declared.
Glucose
For: diabetes · Pro
What you record. The reading, the date and the time, and — if you want — when you took it: fasting, pre-meal, post-meal, bedtime, random. That context is what makes the number readable: 180 fasting and 180 after a meal do not mean the same thing.
What you get back. Two views. Daily draws the curve of that day — the one your vet uses to adjust insulin — and Trend shows the daily average with a band for the day's low and high.
Seizure timer
For: epilepsy · Pro
What you record. Start when the seizure begins, Stop when it ends. Afterwards you can add the severity, notes (how the recovery went, the behaviour after) and whether you noticed anything before — those warning signs that usually only you can see.
What you get back. Past five minutes the app says it plainly: this may be an emergency, call your vet. And if you leave while the timer is still running, it warns you before throwing the recorded time away.
Temperature
For: recurring fevers, infections, post-surgery · Plus (for the chart)
What you record. Reading, date, time, notes.
What you get back. Low, average and high, plus the chart. If you type a value that is impossible for a dog or a cat the app points it out — usually it's the wrong unit — but if the reading is right you can still save it.
Breathing rate
For: heart disease, breathing problems · Plus (for the chart)
What you record. Two ways. Type if you have already counted. Or Count: tap Start, then tap the screen at every breath for a minute and the app does the counting. It's silent — nothing will wake them.
What you get back. This is the number cardiologists ask you to measure at home while they sleep. Low, average, high and the trend.
SC fluids
For: kidney disease · Plus (for the chart)
What you record. Volume in ml, and if you want the site (left, right, other) and how many minutes it took. Recording the site is what makes rotating it actually happen, instead of using the same spot every time.
What you get back. Low, average, high and the trend over time.
Quality of life
For: advanced illness, hard decisions · Plus (for the chart)
What you record. Seven items scored 0 to 10 — hurt, hunger, hydration, hygiene, happiness, mobility, and whether there are more good days than bad. It's the HHHHHMM scale by Dr. Alice Villalobos, the one palliative vets use. You give the scores: the app only adds them up, it doesn't judge.
What you get back. Besides the scorecard there's a Calendar: you tap a day and mark it a good day, an ok one or a bad one. One tap a day, and after a month you can see the direction at a glance without filling anything in.
Lumps
For: masses, lipomas, oncology follow-ups · Free: 1 lump. Plus: unlimited (and the chart)
What you record. You create the lump once — a name, and the position by tapping it on a body map — then add a measurement in mm every time you check it.
What you get back. It answers one question: is it growing? Two measurements are enough for the app to start answering.
Blood values
For: kidneys, thyroid, liver, anything followed with a blood draw · Pro
What you record. You create the test (Creatinine, say) with its unit and — this is the important part — your vet's reference range, then add a value after each draw. Anything outside the range is highlighted.
What you get back. The app suggests the tests usually followed for the conditions you declared: creatinine, SDMA, urea, phosphorus, potassium, T4, fructosamine, cobalamin and more. Tap the suggestion and the field fills itself in.
Stools
For: digestive problems, EPI, IBD, pancreatitis · Plus (for the charts)
What you record. Colour, consistency, amount and a fecal score from 1 to 7 — 1 hard and dry, 3 formed (the good one), 7 watery. All of it optional: if you're in a hurry, pick the score and nothing else.
What you get back. Three charts: the score over time, how many a day (days with none show up too), and the split between hard, formed and loose.
Recording is free on all of them. What changes with the plan are the charts and the views that line your data up over time — and, for glucose, seizures and blood values, the tool itself. The line under each title above says which plan you need.
11 · Insights
The app reads what you've recorded and says out loud what the numbers are doing. It isn't a diagnosis: it's the sentence you'd say to your vet yourself, if you had time to re-read three months of notes.
They're sentences like these — all built on your data, never on averages from other animals:
- Weight is trending down over the last 8 weeks (from 5.2 to 4.7 kg).
- You logged more symptoms in the last 30 days (14) than in the 30 before (6).
- 3 of your last 8 seizures happened within 48 hours of another one.
- The symptoms you log fall most often at night (9 out of 14).
- Recent resting breaths (38/min) are above the range you usually record (22–30/min).
- On mornings after a skipped evening dose, average glucose was higher than after an evening dose given.
- The last stools are looser than usual: score 6, where you usually record around 3.
There's also a Since your last vet visit section: how many seizures, how many symptoms, how many skipped doses and how the weight moved from the day of that appointment to today. It's the summary you need when they ask you "so, how have the last three months gone?".
It takes about two weeks of data before these start appearing. Before that there isn't enough to say anything honest, and the app would rather stay quiet.
Insights is a Pro feature. None of these sentences is a clinical opinion: they are descriptions of what you wrote, made to be taken to a vet, not to replace one.
12 · The report for your vet
This is why all the rest exists: months of notes become a document your vet can read in two minutes.
You start from Generate report on the Home screen, and it's three steps.
- Choose the period. Last 7, 14 or 30 days, three months, a year, All time, or two dates of your own. For a check-up the right period is usually since you were last there. Anything outside the range doesn't go into the PDF.
- Choose the sections. Medications, symptoms, weight, food, stools, glucose, temperature, breathing, fluids, quality of life, seizures, lumps, blood values, vaccinations, visits, documents, pet info and notes, Insights and charts. Each one has a line underneath saying what goes in it. Leave out whatever this appointment doesn't need: a shorter report gets read better.
- Preview and share. You see the summary — pet, period, how many sections — and tap Generate & share: out comes a PDF to email, message, save or print.
Generating it needs a connection: if you're offline the app says so rather than producing an incomplete file.
What your vet finds in it. The numbers that matter on the first page — how many doses were actually given, how many symptoms and how severe, which way the weight is going — then tables with the full detail. It's built to be read from the top: if they have two minutes, the two minutes that count are right there.
On the Free plan the PDF carries a watermark and you get one a month. From Plus the watermark goes and the data also gets drawn: weight, symptoms and the monitoring tools become charts inside the report instead of staying lists of numbers.
13 · The Emergency Card
It's for the worst moment: you're in a clinic that has never met your animal, and somebody asks you what they're on and what they're allergic to.
It opens from the panel at the top of the Home screen. On a single screen it gathers the chronic conditions, the active medications with doses and times, the allergies, the important notes, the most recent symptoms and your vet's contact, which you can call with one tap.
You fill it in from inside it
You don't have to go looking for these fields elsewhere: every empty panel is tappable and opens the field right there — Add vet contact, Add allergies, Add important notes, Add chronic conditions.
Take five minutes over it once, now, while you're calm. The moment you need it is not the moment to be filling it in.
To leave with the vet
Share with vet turns the card into a one-page PDF: send it, save it or print it. It's the sheet to leave with whoever has your animal while you're away, or with the clinic keeping them in.
It works without a connection. The app keeps a copy on the phone, because the moment you need it is often the moment there's no signal: if you're offline it tells you, and shows you the saved copy with its date.
The only case where it has nothing to show is if you have never opened that card on that phone. Open it once at home, and from then on it's there.
14 · Family
A long illness is almost never handled by one person alone. That's what Family is for: two phones, the same data, and nobody giving the pill twice.
Inviting somebody
- From Invite family, or from the pet profile under Family.
- Type the person's email.
- The app generates a link: copy it or share it on WhatsApp, by email, however you like. The link expires after 7 days.
- Whoever opens it signs in with their own Sereno account and accepts. If they don't have one, they create it.
Who can do what
- The owner is whoever created the pet. Only they manage who comes in and goes out, and only they can rename or delete the pet.
- Members can see and update all the clinical data: mark doses, log symptoms, add vaccines and visits. They can't manage the family or delete the pet.
The Family screen shows the members, the pending invites with how long is left on them, and the controls to revoke an invite or remove a member. Somebody who was invited can also leave the family themselves.
What you see of each other. Recent activity on the Home screen shows who did what: "Marco gave Metacam", "Anna logged a symptom". And with the Family activity alert switched on, you get a notification when the other person gives a medication.
From the Plus plan there are also missed-dose family alerts: if nobody logs the dose, the alert passes to the other family members. It's built for the case where one of you forgets and the other can still put it right.
Family and pet limits belong to the owner. If a member gets the invite but has already reached their own plan's pet limit, they can't accept until they make room or move up a plan. Shared pets count towards their total too.
15 · Account, data and subscription
Your account
You sign in with an email and password, or with Google or Apple. If you signed up with one of those two, always use that button to get back in: you don't have a password.
If you forget your password, Forgot password? on the sign-in screen sends you a code by email: you enter it, choose a new password and you're in. If you just want to change it, there's Change password under More.
If you find yourself signed out. Now and then a session expires and the app says so plainly: you sign back in, that's all. Nothing you recorded is lost — it lives on your account, not on this phone.
Language
In More → Language. The app speaks English, Italian and Spanish, and by default follows your phone's language. The report comes out in the language you've chosen: if your vet reads another one, switch before you generate it.
Your data
- Export my data. Prepares a copy of everything you've written, to keep or to take elsewhere.
- Privacy policy and Terms of service, always available.
- Creator code. If you found Sereno because somebody who works with us told you about it, this is where you enter their code so they get the credit. It can only be done once.
- Delete account. Erases the account and everything in it — pets, medications, documents, reports and history. It's final: there's no bin to fish it out of.
The three plans
There's one idea behind it: recording is always free. You pay to see the trends over time, and for how much you can keep at once.
| Free | Plus | Pro | |
|---|---|---|---|
| Pets | 1 | up to 3 | up to 10 |
| Active medications | 2 | up to 10 | unlimited |
| Documents | 5 | up to 25 | unlimited |
| Archived vet visits | 3 | up to 25 | unlimited |
| Family members | 1 | 2 | unlimited |
| Reports per month | 1, watermarked | 5, no watermark | unlimited |
| Lumps | 1 | unlimited | unlimited |
| Trend charts | — | yes | yes |
| Charts inside the report | — | yes | yes |
| Missed-dose family alerts | — | yes | yes |
| Blood values | — | — | yes |
| Glucose curve | — | — | yes |
| Seizure timer | — | — | yes |
| Injection site tracking | — | — | yes |
| Insights | — | — | yes |
You pick a plan from More → Subscription, or from any padlock you run into. It's billed through your phone's store and cancelled there, from your App Store or Google Play account settings. If you change phone, Restore purchases puts the subscription back.
Which one you need. Plus if you want to see the trends and share the care with somebody. Pro if the illness is followed with numbers — blood values, glucose, seizures. If you're not sure, stay on Free: the padlocks will tell you where you're bumping into the ceiling, and that's the moment to decide.
16 · Common questions
Where do I keep the record of annual check-ups?
In two tabs, which together make the medical file. Vet for what happened — date, reason, what was done, the next check-up. Docs for the paperwork you brought home from it.
I can't find the food diary.
It's on the Home screen, but on the Food side of the switch at the top. It doesn't show on the Health side.
I can't see the tool I need.
Tools stay switched off until they're needed. Turn it on from More tools, or — better — declare the condition in the pet profile and the app will switch on the right ones by itself.
How do I add a second condition?
From the pet profile, under Chronic conditions: add as many as you need, and if the one you want isn't in the list you type it in under Other conditions.
Where do I log the weight?
In the pet profile, with + Log weight. Two readings are enough for the app to start showing you the direction.
I marked a dose by mistake.
You undo it from the same row on the Home screen: the dose goes back to being due, as if you'd never touched it.
The course is finished. Do I delete the medication?
No: use End therapy. It moves the medication into the history and stops the reminders, but keeps the logged doses, which the reports need. Delete medication erases those too.
I only give this one when it's needed. How do I set it up?
With the as needed frequency: no fixed times and no reminders — you log the dose when you give it.
My husband gave the pill. How would I know?
If he's in the pet's family, you'll see it under recent activity on the Home screen. And with the Family activity alert switched on, the notification reaches you there and then.
I changed phone. Do I lose everything?
No. Your data lives on your account: sign in with the same email and it's all there. For the subscription, tap Restore purchases.
Does the app tell me what's wrong with my animal?
No, and it never will. Sereno records what you see and puts it in order so that somebody who trained for it can read it. Diagnoses are your vet's job.
