[iOS] MemoMa (Was US$3.99, No IAPs or Ads)

MemoMa is a note app that uses your calendar as a storage. It’s up to you whether you use it as a journal or as your calendar app. Supports Apple Watch as well.

Personally, I like the interface quite a lot.

Description:
MemoMa saves your notes in your calendar. You can also watch your photos and add comments.

What's possible:
Saving notes in the calendar.
Registering frequently used words for fast typing.
Viewing photos.
Adding comments to photos.
Search notes with multiple keywords
Apple Watch: Writing and reading notes.
Apple Watch: Checking calendar events.
