About this app

"Is my rabbit eating less than usual?"
That small observation could be the first step to protecting your rabbit's health.
usagi Diary makes daily care visible and helps you spot changes early.

[Made for rabbits - done in 30 seconds]

Food amount, weight, droppings, urine, water intake, grooming, vet visits, medication, and diary. 9 categories designed just for rabbits. No unnecessary steps, so you can keep it up every day.

Reorder the categories or hide the ones you don't need. Customize it to fit your routine.

[Calendar view for the full picture]

Every entry shows up as a marker on the calendar. Tap a date to instantly see that day's records. Perfect for preparing before your next vet visit.

[Weight chart catches changes]

Track your rabbit's weight over time with a visual chart. Color-coded zones based on veterinary guidelines show you at a glance what to watch for. Charts up to 1 month are free.

[Multiple rabbits welcome]

Register as many rabbits as you like. Switch between them with one tap and manage each health record separately.

[Celebrate birthdays and anniversaries]

"She turns 3 today!" "100 days since coming home!" Birthdays, anniversaries, and milestones are celebrated automatically. Your daily entries become memories too.

[Premium for deeper insights]

- Weight chart from 3 months to all time
- Breed-specific growth curves for comparison

All recording features and the weight chart up to 1 month are free.
