Whatever the life stage
Sereno fits, from first shots to adulthood.
Puppy & kitten
Vaccine schedules, growth and first vet visits.
Adult
Routine care, weight trends and the occasional scare.
Senior
Chronic conditions, more meds, closer monitoring.
No ads inside the app
No banners, no videos to dismiss. Open it, mark the dose, that's it.
One report for the visit
Pick a period and Sereno builds a PDF: doses given and missed, symptoms with dates and severity, weight, lab values and past visits. Open it in the exam room, or send it ahead.
Two people, one pet, in real time
Invite whoever cares for them: they join with their own account and pay nothing. Mark a dose and it appears on their phone straight away, with a notification saying who gave it. Nobody gives it twice.
Care, on every screen
A guided tour through your pet's whole health story.
- TodayEvery dose and task for the day.
- MedicationsDoses, schedules and refill reminders.
- SymptomsLog a flare-up with a note, a photo and a time.
- Health reportOne tap turns months of tracking into a report.
- Food & waterLog every meal, treat and sip.
Everything chronic-pet care actually needs
Powerful where it matters, calm everywhere else.
Insights
Sereno reads the data you've already entered and shows you the patterns in it: what's above or below your pet's usual range, what tends to happen at certain times of day, and what has changed since the last vet visit.
This is a pattern in the data you entered. It is not a diagnosis or a cause, and does not indicate any disease. Discuss your pet's health with your veterinarian.
Medications
Schedules, smart reminders and refill alerts.
Symptoms
Quick logging with photos, severity and time.
Vaccines
Full immunisation history with renewal nudges.
Vet visits
Notes, diagnoses and follow-ups in one timeline.
Documents
Lab results and prescriptions, scanned and searchable.
Family sharing
Everyone caring for your pet, always in sync.
Stool tracking
Colour, consistency, amount and a 1–7 score (1 hard and dry, 3 formed, 7 liquid). Three charts: the score over time, how many a day, and the split between hard, formed and loose.
Monitoring
Track temperature, resting breathing rate, fluids, quality of life and weight over time — and map lumps on a body diagram so you always know which one you're looking at.
Charts inside the report
From Plus: weight, symptoms and monitoring tools don't stay lists of numbers — they're drawn as charts inside the PDF you take to the vet.
Emergency Card
One screen with conditions, active medications with doses and times, allergies, important notes, latest symptoms and your vet's number, callable with one tap. It works with no connection, and shares as a one-page PDF.
Seventeen conditions, each with its own tools
Say what your pet has. The right tools switch themselves on.
- Diabetes
- Epilepsy
- Oncology care
- Kidney disease
- Heart problems
- Cushing's syndrome
- Hyperthyroidism
- Arthritis / mobility
- Senior pet
- IBD / digestive
- Allergies
- Anxiety / behavior
- Megaesophagus
- Myasthenia gravis
- EPI (pancreatic insufficiency)
- Addison's disease
- Hypothyroidism
Declare the condition in the app and Sereno enables the tracking built for it. Works for any other ongoing or one-off concern too.
From chaos to clarity
Scribbled notes, reminders and half-remembered dates become a calm report your vet will love.
