See your records add up

You wrote your hundredth entry and the app said nothing. Now a badge moves up a level as your records grow.

Screens are shown in Korean. The app itself is fully available in English.

Five levels per feature
Diary, profiles, anniversaries, events, memos, to-dos, routines, timer, ledger, business cards, rating sheets, quotes and timetables each have a badge. As records add up it goes bronze → silver → gold → platinum → diamond.
One record gets you bronze
Leave just one record and you earn bronze. There's also an Explorer badge that rises as you try more features.
Next level and a shortcut
Tap a badge to see what each level needs and when you earned it. Tap 'Try it' to jump straight to that feature.

It also does this

A celebration pops up when you reach a new level. 'Go see' opens the badges screen.
Everything you've already recorded counts. The first time you open it, you're told about all the badges you've earned at once.
Badges earned by restoring a backup are marked 'Earned' without a celebration.
Find them in More > Achievements > Badges.
