Description by Ota Sato Written by the developer, not by AppBrain. Click to read.
Little moments with your pet deserve to be remembered.

Uchinoko Diary helps you capture everyday life with a photo and a note of up to 60 characters. From sleepy afternoons to a favorite toy, keep the moments you’ll want to revisit.

• A simple daily diary
Save a photo, add a short note, and use stamps to capture moods and highlights. You can edit saved entries later.

• Your days at a glance
Browse photos and stamps in the monthly calendar, or find past memories in the diary list.

• A month of memories on one album page
Choose a favorite photo entry from each week to create a monthly album. Personalize it with backgrounds, frames, and title decorations you’ve unlocked.

• Sit back and revisit photo memories
Replay photo entries from a selected month in random order. Pause whenever you like or move between entries.

• A profile full of personality
Keep your pet’s photo, name, birthday, age, personality, and special talent together. Adjust the position and zoom of the profile photo.

• More to collect as you keep writing
Unlock rewards through diary milestones, seasons, and your pet’s birthday. Watch an egg crack open to reveal album decorations, app icons, and diary backgrounds.

• Your pet on your Home Screen
An iPhone widget shows the profile photo, today’s diary status, and your writing streak. Tap it to open today’s entry.

For dogs, cats, rabbits, hamsters, guinea pigs, parakeets, finches, goldfish, rice fish, turtles, and other beloved pets. Make room for their everyday moments, at your own pace.
