I rarely if ever given up a review. But this is a great app with lots of functions and choices. Give me an option to pay for a no ads version at a reasonable price and this is easy five stars. UPDATE: It's great to earn money and you should do that! What I was saying is that I would like the option to PAY you in order to have ads removed from MY copy of the app. I wasn't bashing your ad revenue model. We all have to make money.

I highly recommend this app,have been using it for the past 4 years, and the way that you can change the wallpaper on the lock screen is absolutely amazing!! everyone who needs to have the apps locked can also have videos and folders locked too. its insane how you can secretly capture the image of the person who can't open the lock. And I also like that you can hide the app icon. its just amazing. but the only thing are ads. they just keep popping up at certain times. anyone wo needs this instal

App lock is great but it has a huge problem that needs to be fixed. Sometimes, this app doesn't work and will leave everything unlocked. It's a huge risk and I have to open app lock again and then it starts to work again. If this problem is fixed, then it definitely deserves a 5 star rating.

Hi Mohammad, sorry for the problem you encountered❤️. Could you tell us more details about the problem via "Settings - Feedback or suggestion"? Did you clear the background running apps? App Lock will run in the background and hide itself to avoid being seen by intruders. So please avoid ending all background apps at one time. Best regards.🌹
