It only works when I close the app which I wanted to lock then opened this ultra lock app and then open the app I wanted to lock otherwise when I open the app I wanted to lock, and I unlock it and close the app and open it back again it doesn't lock. Thanks it does work now. (edited)

Liking this app alot. Better than other app locks. However, this app can be disabled without entering the code by pressing FORCE STOP in app settings. Yes, one can app lock settings, but is it possible to have it so necessary to enter code to force stop?

If I could give 0 stars 1 sould it is absolutely trash you can easily open the apps even without the password and the uninstallation feature absolutely sucks I installed this for my son the next day he has already figured out how to open apps then he easily uninstalles the app with the uninstallation feature enabled absolutely horrible

This is a very great app to use especially for siblings who always go through my device but I would like to request a function to be added in which, when someone uninstalls a lock app the app would request a password to uninstall it because my siblings deleted my app which was locked
