personally, I like this app. a bit slow to work, but overall a good app. a bit of adds, but it's not a huge issue. it lets you set ur own password or wtv and automatically locks some apps which you can choose to keep locked or not, even has an AI chat bot so I can ask for help if u don't understand smt. sorry if this wasn't much help, kinda rushed lol.

Good at first, but lately they have started giving me ads sometimes when opening locked apps. These are easy to skip because you can just close the ad by closing applock but they're still giving me ads so I have to leave one star. I will keep using it because I'm used to it, and I will keep skipping out of the ads, and I will keep one star until they remove ads. Edit: The devs responded to the original review using AI btw... I've also noticed ads getting more frequent over time, might uninstall

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.

The app is free. It gives you the option for biometric unlocking (face and fingerprint) or 4 - or 6-digit password. Ads do pop up if you have that app locked, but they barely pop up, like I barely see them. (Also, if you just close out of the app while an ad is showing and re open it the ad won't be there anymore) I love this app! it gives you privacy, and it's not one of those apps with a bug that destroys and takes over your phone. It also takes pics if someone get the password wrong! 🤭😭
