Pet Care Android App with Vaccination Reminders and Vet Appointment Booking

Pet owners miss vaccinations and vet visits not because they do not care, but because the dates live in scattered places: a paper card at home, a message thread with the clinic, and memory. This app keeps all of that in one place, so nothing depends on remembering a date months ahead. Owners record each pet once, with species, breed, age and weight, and the app tracks that pet's vaccination schedule from templates. Each template carries an interval in days, and the app adds that interval to the last vaccination date to produce the next due date, then reminds the owner 3 days before it (design target). When a visit is needed, the owner picks a clinic from the vet directory and books a time slot. Health notes and weight entries sit beside the same pet record, so the owner and the vet see one continuous history.

This is a built-to-order software project: the Android app, demo build with sample pets and clinics, and the complete viva kit (report, PPT, Q&A) are prepared fresh for you.

The Problem
A missed booster is rarely a deliberate choice: immunity lapses quietly, a puppy's second round slips past its window, and a vet visit gets postponed because booking meant finding the clinic's number, calling during working hours, and hoping a slot was free. The Pet Care Android App with Vaccination Reminders and Vet Appointment Booking answers that gap by turning scattered dates into one managed routine. Each pet's vaccination schedule is computed from its last vaccination date plus a template interval, a reminder fires 3 days before the due date (design target), and the same record that holds the pet's species, breed, age and weight also carries the clinic booking that closes the loop. Without that loop, owners juggle paper cards, clinic messages and memory — and the pet, which cannot remind anyone itself, is the one left unprotected when a date slips.

The app works end to end in one loop: pet profile, schedule, reminder, booking. First the owner creates a pet profile with species, breed, age and weight, and the app stores it as one record in the on-device database. Next the owner attaches vaccination templates to that pet — for example a rabies template with a 365-day interval — and the app computes each next due date by adding the interval to the last vaccination date. As a due date approaches, the app raises a reminder 3 days before it (design target), so the owner has time to act rather than discovering a missed booster. The owner then opens the vet directory, picks a clinic, and books an available slot for that pet. After the visit, the owner marks the vaccination done, which recomputes the next due date, and adds a health note or weight entry to the same pet record. The loop then repeats for the next due date.

1. The owner creates a pet profile with species, breed, age and weight; it is saved as one Room database record.
2. The owner attaches vaccination templates to that pet; each template carries an interval in days (for example 365 days for rabies in the demo).
3. The app computes each next due date as last vaccination date plus the template interval, and schedules a reminder 3 days before it (design target).
4. The reminder fires on-device, and the dashboard surfaces the due vaccination under upcoming care.
5. The owner opens the vet directory, compares clinics by distance and hours, and books an available slot for that pet.
6. The booking appears under upcoming care with clinic, date and time.
7. After the visit, the owner marks the vaccination done; the app recomputes the next due date from the new date.
8. The owner adds a health note or a weight entry in kilograms to the same pet record, closing the loop until the next due date.

The app's strongest capabilities are its pet profiles, its vaccination reminders, its vet booking, and its health record. Pet profiles hold species, breed, age and weight for each animal, so every reminder, appointment and weight entry belongs to the right pet. Vaccination reminders are computed, not typed in: each standard schedule template carries an interval in days, the app adds it to the last vaccination date, and a reminder fires 3 days before the due date (design target). Vet booking turns a directory of clinics into action — the owner sees distance, hours and open slots, then books a time without a phone call. Health records and the weight log sit alongside these, giving each pet a simple history of notes and weight entries in kilograms. Together these four capabilities cover the daily reality of pet care: know the pet, know the next date, book the visit, and keep the record.

• [Pet Profiles — Implemented] One profile per pet with species, breed, age and weight, plus the last vet visit date. Every vaccination, appointment and weight entry points at the same pet record.
• [Vaccination Schedule Templates — Implemented] Standard schedule templates (for example rabies, DHPP and FVRCP) attach to a pet, each carrying an interval in days. Templates are starting points for the owner to confirm with their vet, not veterinary advice.
• [Due-Date Reminders — Implemented] The next due date is computed as last vaccination date plus the template interval in days, and a reminder is scheduled 3 days before it (design target) using on-device scheduling.
• [Vet Directory and Slot Booking — Implemented] Clinics are listed with distance, hours and bookable time slots; the owner selects a slot and books it for a chosen pet, and the booking appears under upcoming care.
• [Upcoming-Care Dashboard — Implemented] One screen shows pets, upcoming vaccinations and the next appointment together, so the owner sees what needs attention without opening four screens.
• [Health Records and Weight Log — Implemented] Dated health notes and weight entries in kilograms are kept per pet, with a simple weight trend over the logged months.
• [Appointment Management — Implemented] Booked appointments are listed with clinic, date and time, and can be viewed alongside upcoming vaccinations for the same pet.
• [Offline-First Local Storage — Implemented] All pet, vaccination, appointment and health records live in the on-device Room database, so core screens work without a network connection.

Optional customizations (not in the base build): cloud backup and sync across devices, a clinic-side panel for managing slots, multi-owner sharing for one pet, and extra pet fields such as microchip number. Future scope (not in the base build): medication reminders, a vet-side appointment confirmation flow, and weight-trend insights such as steady gain or loss alerts.
