3Q Memo Diary - Notes, Planner

A diary and a notepad in one — simple enough to actually keep using.

Photos, voice, handwriting, moods, and weather, all gathered into a single book with just a few taps.

Save your daily memories and quick notes — starting today.

3Q Memo Diary works as both a journal and a notepad. Write a thoughtful diary entry, or jot down a quick memo — switch between the two however you like. Even if writing isn't your thing, tap to log your mood and weather, and pick a photo from your library. On busy days, a single photo or one-line note is all it takes.
