It works majority of the time, however, there has been a huge problem whenever they update the app that forces me to have to reinstall. I can live with that. The biggest issue is how the fingerprint scanner rarely pops up when I open up an app. I'm using the z fold 7 and it rarely asks me for my fingerprint. I don't want people watching me use the pattern, but that's what I'm stuck having to use majority of the time.

I have Google Play Pass so I was able to get the premium version of AppLocker. The app works like it should and the "magic" features, like random keyboard for pins, is useful. The one thing that's missing is a location- or WiFi-based lock feature. I'd like to select addresses, like my home or home network, where I don't need my apps locked. Once I leave my address/disconnect from my home network, the app should activate automatically. That would make it 5 stars for me.

It's pointless. When you press the App history button on your phone (bottom far left or far right), it shows everything you were doing on all of the Apps . No one else is able to unlock your pin, but they can still see your previous messages, calls, emails, files, pictures, just by pressing the App history button. This is a major fail and must be corrected.

The app was pretty intuitive and easy to setup and use. The free version is useful but the advertisements were quite obtrusive. I ALMOST bought the app until I realized it could be uninstalled without a password. Just go to the app drawer and uninstall it. I thought the purpose of an app locker is to add a second layer of security to your device by preventing somebody from accessing certain (or all of your) apps. It isn't much of a security layer if an intruder can simply uninstall it. The app does auto-run when the device starts up but it does't auto-run fast enough and I was able to start locked apps upon start-up of the device.

I didn't last a day. The video ads were annoying and became more intrusive throughout the day. Often I would open an app, put in my password, watch the video then it would open the app only to lock it. This would go in circles until I gave up, closed out and tried again. This glitch, along with the intrusive video ads after ever unlock, lead me to delete this app to find a better option for me.

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.
