Great app. It does do what it says. It is easy to use. However people can still see what's in the locked apps in your "recent apps" . Also, sometimes it doesn't really lock the apps. It will glitch and allow them to be opened. The number of ads has become ridiculous. Every other time I want to access a locked app an ad pops up.

This app works awesomely for keeping the people you don't want out of your personal stuff. But you can still access and delete the apps you've locked if you go to >Settings >Apps >Recently Opened apps in settings, I recommend fixing that or coming up with a solution. I lastly hope you can make the Thief Capture system more versatile so it works better offline. Other than that your software is excellent. UPDATE: Now when I hit 'Forgot Password', it buffers for a second and then says 'error'.

I've been using this app on 2 kids phones for awhile and it was great. However, this week we changed to new phones (still higher end Samsungs) and suddenly the app doesn't work reliably. It takes a while to start when the phone is restarted which is on one hand understandable and on the other unacceptable and randomly just does not lock anything unless I go into the app and turn off and then back on. It's exempt from optimization so it's not that. Just isn't working for me anymore.
