Human remembers much easier one pattern as several series of numbers.
Think you own pattern in 4*12 matrix, and save all your pin codes using that same pattern.
The matrix can be public, but only you can find the correct pin code from the matrix.
You can use this also to save passwords, or to generate a random password.
Instead of pin code or password one item could be a note.
If the note is enabled for notifications, you could see the notes very easy without unlocking the phone.
F.ex
- to do list
- shopping list
- ICE (In Case of Emergency) information
- etc
In this trial version you can test the app with two pin codes (items).
If you like please buy the full version with 30 items and possibility to auto save hardcopy of each item.
