Ratings and reviews

Reviews are Probably Bought This app lock other apps on the phone but has many issues. First of all, it glitches. For instance, I can see a preview of my messages right before the lock screen appear for me to put the password to actually access the app. Secondly, the app is FULL OF AD. ANNOYINGLY FULL OF ADS. You won't be able to open an app right away without first seeing an annoying and random ad for 10-20 seconds. Good luck if you're in a hurry. I am deleting the app right now.

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.
