## What is PonNikki?

The one-time purchase version with no ads. How was today? Just tap a tag to stamp it. A diary that keeps going, even when you don't feel like writing.

Main features:

- Tag stamps: Tap a tag like "#DidMyBest" or "#Chill" and today is recorded. Add as many of your own tags as you like.
- Write when you want: Add notes and photos (up to 10 a day; pick one as your featured photo).
- Look back on a calendar: Your featured photos and tags fill a monthly calendar, so you can see your month at a glance.
- Plans: Add plans with an emoji and a title. See this week's plans on the Today screen and on the calendar.
- Today's Card: Turn your photo and tags into one image to share or save. Choose default or your own stamps.
- Habit checks: Check off daily habits. Streaks and 5 characters (boy, girl, cat, dog, finch) cheer you on. You can edit their lines or add your own character.
- Reminders: Get a reminder at the time you choose.
- Look Back lock: Protect past entries with a passcode and Face ID or fingerprint. Today's entry is always quick to open.
- Themes: 20 color themes plus your own custom theme.
- Backup: Export and import all your data as one file when you change devices.
- Private: Your diary text, photos, tags, and habits are saved only on your device. Nothing is sent or synced to the cloud.
