AppLock Master Customer Insights

1. This is one of the best Applocker actually.Am rating this app with four star's because sometimes it deactivates e.g when I locked my WhatsApp and tried to open it I was requested to put the password as the norm but after a few minutes or hours I go on WhatsApp it won't ask me to put the password if anyone tries to invade my privacy they could totally invade it because this app deactivates itself unknowingly which is wierd 🤨😤.Who ever created the app hats off first i don't need to worry because my brother can see my lock but in this it's not like that it has a pattern size that allows a big pattern or pin that's it can't speak about that but yeah seriously this app is like a legendEvery single time my screen goes to sleep I have to start the app or it don't work!!!!! The point is to keep my kids safe NOT LET THEM DO WHAT EVERAll features are the best of this app locker, just in purchases...

2. If an ad-free version of this app exists, I won't be buying it.After two to three days, the password is removed from the locked applications and it is showing the status as locked but when opened, there us no password at all.

3. I 100% understand the need for ad revenue on a free app, but at the rate of SEVERAL full-screen ads per minute—PLUS banner ads—that's WAY over a reasonable limit, and interferes with the app's basic functioning.

4. But the only problem I have with this app is that can't we use different passwords for different apps ? It would be very helpful if this feature was added.Dev, please improve & optimize the AppLock Master to be activate instantly or more quickly after Phone Restart & Power/ Switch On.

5. The best part is temporarily unlock , we have not to put password again and again.Good app , best performance, and customisable theme, so I gave it 4 stars.

6. Just during the time of trying to choose my settings, there was a full screen ad after EVERY click.

7. All the application has to be locked again.

8. Please make a note of this issue.I found everything perfect with this application.

9. Had it for 10 minutes.

10. SINGLE.
