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
If interested in only app lock ,
For Marshmallow & Lollipop screen lock OR only screen lock ,
