Useful pin lock Some time cannot display the unlock chart please fix it immediately...
Great app but needs to be longer then 4 digits long to stand up to brute force attacks. Sound concept though.
Works good but I wish there were more algorithms and it doesn't work for the lock screen on lollipop. I really only got this for the lockscreen.
It's a good idea I like the app and the idea behind it but I cant get it to work with the lock screen. Could use some work
Validation code does not show on lock screen moto e2nd gen
Back to being excellent! An earlier update had broken this app, but the latest update fixed them all. The developers were very responsive and fixed the issue quite quickly......

Matrix overlap in practice resolved .
