The 1Memo app is a new notes app designed specifically for minimalists. Unlike other note apps which offer multiple functions, 1Memo does one thing only. Users can only make and see three cards (notes): one for yesterday, today and tomorrow. Notes can be saved as images, but other then that there's no way for the app to show you what you were supposed to do a week ago.
Again, that's by design. The 1Memo app wants users to live in the present and not think too much about what's past or coming. True to its minimalist roots the app has a clean design. While it may not be for everyone the 1Memo app should be attractive to those who prefer stripped-down productivity apps.
