Not very impressed with this app lock. The fingerprint feature is nice and also very necessary because I'm constantly having to unlock an app with it- even if I've just used the app. Other lock apps have a feature that permanently unlocks a just used and unlocked app until the screen is shut off (at which point they'll lock again). Biggest con is that this app likes to close randomly by itself so all previously locked apps are now unlocked until you go back into this lock app and reset it again.

This app is by far the best, compared to other applock apps. I encounter very few ads and it has all the features that the other apps, the difference is that the features actually WORK. I gave it 4 stars because there is no way to change the theme of the app. By theme, I mean background picture and all.

I tested the ' forgot password ' several times, and i am still waiting for the emails with the reset code, and said it would send a password via my designated email address in the app, IT NEVER SENT ANYTHING ! lucky for me I had not protected any of my data / apps. STEER CLEAR OF THIS APP or you will find you will have to reset your device to factory settings if you forget you passphase / passcode. I would suggest everyone using this app test the email settings to verify you will receive an email with a reset code. Unlock all the settings / spps/ everything before you do ! Uninstalled !

I would say that it isn't a good app for lockig. It is so irritating that when u lock the apps and they unlock by itself. And also, any app could be unlocked even by entering a wrong passcode. I am damn frustrated with this app. Please fix this problem.

Great app - simple, yet locks all you want locked, including Settings. Totally worth it. BUT: 1) In Samsung Note 9, if you lock Settings, Samsung Secure Folder fails. You must choose 'tween that & this app. I choose the app, coz SSF doesn't lock Settings. 2) Contacts has 2 access points - the Contacts icon, and the Contacts tab in the Phone app. When Contacts is locked, only the icon access is locked - access via tab in Phone is open 3) Hope you can include Password access - more secure

Ok App. Banner ads cause screen to jump up when typing in password so you miss the number your going for . No time delay for re_entry to an app which is annoying. Update Recently I often have to type in passwords twice and some apps won't open at all just leaving a black screen, so I am uninstalling.

Fantastic app in every way. It's so easy to use and works flawlessly. The developer has paid great attention to detail and seems to have thought of everything. I had no hesitation in purchasing the ad-free version.

I've used this App Lock for a long time and I'm a premium user. I've never had problems using this App Lock but I just got a new phone and it's updating to Android 12 I'm going use this like I always have. Hopefully it works as good as it always has.

Totally awesome app 😊 no bugs, no glitches and best of all has the exact options i'm looking for to keep my device safe! I highly recommend, it's basic but at least it's actually working!

Mad. G. Jul 22, 2019     

not great. works... but would like numbers scrambled for better security. also having to re-enter code after switching apps for less than 30 seconds is a huge pain.

Easy to use. Ads are not big and annoying. We use digital Bible app at our worship meetings, by blocking other apps my son stays focused because he cannot venture into other apps. It also helps me to stay on task and not venture off.

This app is the best as I want. I don't prefer any other app lock except this Just one bug to fix sometimes it doesn't work , especially when we are offline. Just this is the reason why I am giving it four stars. Please fix this bug , unless this app is very nice.

What can I say, this meets meet the high expectations they set forth in their description. It is truely a lock with locking within yet more locks. If your job is a sensitive nature, or its privacy is needed to keep you and your clients safe, then this is the app you need!

Tra. L. C. Aug 24, 2020     

This app needs to be a little bit faster to locking apps this app needs an option to unlock every time when you turn your screen on instead of every time you exit the app that you have locked so far this app is it looks nice and good.

Sal. L. Mar 14, 2022     

It doesn't work most of the times and only consumes my battery with a forever appeared notification.

Pas. S. Jun 2, 2021     

App is clean, simple, and works. I would love a text-based password option though, rather than just pin or pattern.

Best Free App Locker on Play Store. I've already tried more than 12 App Lockers Before This. But Every App Either Had Glitches or A Ton of Ads. This is Exceptional and Best 👌 Try Once, You’ll Love it! So Smooth and Responsive 👌

Such a real encryption. Loved this app. If there is something more than 5 stars i would really do that for this app. It has the commercial grade encryption and a secure secrecy. Thank you Smart Mobile Tools for providing such a satisfying security.

Needs option to unlock only after screen lock,but not everytime. Please update app with this feature. I bought payed version. So for this only 4 stars. Overall great app. Works on android 11.

Mig. R. Aug 25, 2021     

Pretty easy to use & I really like having the option to lock my apps individually or all at once! HIGHLY RECOMMENDED!!!

This is the closest thing I could find next to bear lock that works the same, where you can lock individual apps like YouTube. My son had time constraints and limits there & App Lock works great for that. Do wish I could use something besides the pattern lock though.

I'm giving it a star because it doesn't keep apps safe all the time, it disables itself. The only way it works again is by entering into App lock again, it makes me tired because I have to do it about 10 times a day, otherwise I will give a 5 star.

Mar. A. Oct 16, 2020     

Seems to be working to lock and unlock apps with pin, but not fingerprint and my print reader works on other apps. Wou be 5 it Stars with fingerprínt reader working....

Rel. R. Apr 24, 2020     

It's a great app. It locks almost all the applications so you can be guaranteed that no one will see what they're not supposed to see on your phone. BigUps for the Developer 👌

And. D. Mar 31, 2020     

i think its the best app lock. Id like to ask for favor. Could you please make it so we can add our own backgrounds? Then the app would be unstoppable.

Jos. W. Jan 15, 2019     

it's cool and better from the other app locks but also needs a better improvement. you can add *Self intruder * and many more to shape it well...thanks
