I only gave it 2 stars because, I had this app downloaded for YEARS. It worked phenomenal! I had it on a timer, to turn the locks on and off.. Super easy to use. Just worked great. Then, sometime over the last few months, I noticed that the timer didn't work. Okay, so I was turning it on and off manually. Now? It doesn't lock a thing. Extremely disappointed. Useless... uninstalled...

I didn't have any problems with the last version. The upgraded version is awful. It will play an Ad after every single thing you do which it didn't before & once the Ad plays it kicks you out & sends you to play store to install it. The only way you can get out of it is by closing it which sometimes takes several attempts. I've had this for years but it's not worth the fight & frustration. . NEW PROBLEM! Woke up today & all my pics are gone!! I was in the middle of backing it up. Lost everything

I see you raised your prices. I hate subscription apps. Edit: I understand and appreciate your need to make money. I don't need it that bad any. My phone series has built in secret folders. So the app was redundant security. I was willing to support for a nominal one time fee. Not a never ending subscription. Not a fan of ads either. Choosing to part ways. Thanks for the years.
