Search "Pin code help trial"

This is the full version with max 30 pin codes.



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

If enabled the matrix is stored as hardcopy to the memory of the phone.
Only in this case the Android permission "Storage" is needed. The app doesn't read or write any other information of the memory!
