AppLock Master user reviews :

Very good application overall. The only issue is sometimes it doesn’t work especially when you restart phone and open AppLock protected applications, they open up without asking for the security key. The same happens sometimes when you just open up your phone and use applications. These are some loops need to worn on.

Edit: Now not working perfectly with Android 11. After restarting, the app is not activated instantly ! Anyone can access the locked apps after restarting the phone. Fingerprint doesn’t work. Please fix. Earlier 5* – Excellent app. Working with PIN +TIME as well as the device fingerprint. Not draining battery. Impressive !

It is sooo useful.we will hide any important information in our apps that other cannot see.claimed to be vulnerable to hackers. Having an applock for iPhone or Android device is useful. It is suitable for security and keeping people out of your business.claimed to be vulnerable to hackers. the security feature is to lock your Android apps so that nobody can access or uninstall them, but applock can hide pictures and videos, and even contacts and individual .it’s good and useful for all people

The overall performance is good. But there is a single problem which appears after the startup. The protection is disabled during the initial stage of the startup. After few minutes it will protect each application from unauthorised login.

My Android has issues and effects the last 3 applocks I installed in the last few mos. So, now this app works basically if I tap it. It has been compromised and blacks out. Waiting for my other phone so I can Factory Reset this old phone. I liked this app but I noticed android and android apps, for a few mos now, have been breached.

I like the system of the app and also you can change the lock screen theme so for me it’s gd bcz without it I will very simple and than I think that I dnt really like to use this app. So for me over all its pretty gd to use

I found this app very useful and easy to setup. Features provided in the app are just what I have been looking for to restrict the access of my kids to some apps and folders.

This app is completely cool. It provides an indestructible lock. And I love it a lot. It’s fast , easy and you can take charge of ur privacy. It has different kinds of lock  which is the most fascinating thing here

This app is very good like if you want to lock some applications or hide some photos or videos tgen you can and the best part is it also has some really good options too and also if you lock any app and you don’t want anybody to know whether you have locked that app then it gives you free fake covers I am so satisfied with this app never had any experience like that. and it doesn’t contains alot of adds
