Ratings and reviews

Saw good reviews and thought to give it a try. Lets you set a code and do Bio locks like fingerprints. You can choose which apps to lock and to have unlocked and to open the lock app or try to delete it, you have to put in your codes. It has a one star because it's honestly annoying to have to put in a code and fingerprints every single time and the ads are stupid. I'm an android user and my battery is draining super fast from this app, by itself. 10% lasts me about 5 minutes until its at 5%.

Update: More than 3 weeks after first contacting customer service and almost 3 weeks after leaving 1 star review and complete silence from customer service regarding any solution. I purchased AppLock Pro. It does not work. I've been in contact with customer support, who keep telling me to do the same thing, which doesn't work. I've uninstalled and reinstalled the app. I have manually selected "restore purchases" via the app.

Android user here. It took about 10 minutes to figure out how to get around this app’s “lock” system. Since it relies on ads, turning on airplane mode lets you open messages without any lock. Even with service, you can still swipe up and hold to view message previews through the app switcher. So it’s not really secure—more like a basic layer that’s easy to bypass.
