  1. Petra-avatar

    Generally, app is very good. Especially the decoy password. It is well thought. But there is a problem with it. When i open the fake photo folder and close it and then open it again, it opens the real photo folder and we can see the photos. You really should fix that.

  2. Jonas-avatar

    Great app. But for some reason I can't move pictures from the gallery into the vault anymore. It just won't finish "Loading them"

  3. Adetayo Adejumo-avatar

    Adetayo Adejumo


    Very good and stable. One of the best apps on the Play Store. Wish we could lock audio files too.

  4. SylAriLil-avatar

    There's a bad bug that basically locks the whole device and the only way to get rid of it is to reboot the whole device. It gets stuck in a loop where you have to put in your password and unlocks only to lock back up instantly and it has you repeat that process. Even if you press the home button, it stays stuck in that loop. As I said, only way of getting out of the loop is to restart the whole device. I can't stand getting stuck in that loop. I have to uninstall the app. I'll try it again sometime in the future as I love the Augustro Music app. It's the music app I've been mainly using for the past 2 months. So I'll give this app a second chance later.

  5. Abinash Acharya-avatar

    Abinash Acharya


    It works all right, however I have an issue with the way it unlocks. It accesses the vault automatically when I type the code on calculator. This makes it very prone to accidental unlock by someone trying to use the calculator and incidentally entering the same number sequence. A different app I use uses the % key "Meaning "xxxx%" is the way to access vault. Please make required changes for it to be more secure.

  6. Edward Garza-avatar

    I like the app, but I notice some apps don't get protected by the App Lock feature. For example Mega and Firefox Send don't give me the "oops the app is currently unavailable" message when I open them. Could be because Mega already required a password to open it, and I think Firefox Send is still relatively new? So maybe these after contributing factor.

  7. A Google user-avatar

    I recommend all people to buy this app, it has a lot of features for small price. Features worth beyond money. Some companies set tons of price for small features this is opposite to this. Very happy. Everyone should have in ur mobile /*keep releasing the app like this */. Good team and good support and reply and also some company say to solve your problem but no updates but this developers are very supportive. Can't say my joy try this app by installing. Great concept👌👏🙂☺️

  8. Robert Owens-avatar

    amazing app the in-depth thought all the way through from precautionary measures to implementation of a defcon 1 situation they've thought about everything.

  9. Colin Wilson-avatar

    Works incredibly well. The idea of having a fully functioning calculator that also doubles as a vault allowing me to keep confidential photos and videos away from prying eyes is brilliant. Files are secured inside the vault too, not just made invisible from other file and picture browsers. Works brilliantly on my moto g6 play, but sadly not on my Alba tablet running android 8.1 which is a shame. But I'm still very pleased with it.

  10. Roman Agresti-avatar

    This is the best app for hiding things in plain sight! A completely discrete fully functioning calculator to use as a daily tool--- plus upon entering the correct sequence of numbers (up to 12 digit pin if memory serves me) opens up to display hidden files and pics. No ads, no bs, just secured items and apps for my eyes only. Make this app even better by adding more advanced calculator functions for those in need of graphing or equations, (ohms law etc) . Why do you need 2 calculators hunny?? A+

  11. Pranav Pranav-avatar

    Marvelous calculator vault ever. "Some company sells low featured apps for high price by cheating customers".This is dead opposite to above statement. Has tons of features. Price is highly acceptable. No words just try it. Recommendded highly for all. Thank you for solving all my listed bugs, developers. Keep releasing new apps like this 👌👏👏👌🙂🙂

  12. TECHNOFICTION-avatar

    concept is very nice . but its not hiding the contents from memory card. we have the option to add the contents from memory card to vault . But the same contents are still accesable from a file manager and in gallery also . plse resolve it , otherwise there is no use of it .... i have already tried reinstalling the same . Am using redmi note 5 pro and my friend is using samsung j10 , he is also facing the same prblm

  13. Goku Dorz-avatar

    Easy setup, if you don't know this app you can't tell the difference between a normal calculator app and this vault

  14. A Google user-avatar

    Way too many unnecessary permissions and obviously fake reviews not to be spyware: This app has access to: Device & app history retrieve running apps Identity find accounts on the device Contacts find accounts on the device Photos/Media/Files read the contents of your USB storage modify or delete the contents of your USB storage Storage read the contents of your USB storage modify or delete the contents of your USB storage Camera take pictures and videos Microphone record audio Other update component usage statistics close other apps receive data from Internet view network connections full network access run at startup draw over other apps control vibration prevent device from sleeping modify system settings Google Play license check

  15. Varró Olivér-avatar

    the app works great, has really advanced security, apart from a password, however, I do have a complaint: the pictures that are stored, are zoomed in a little. Would like to see a fix :)

  16. Michael Dee-avatar

    Nice concept, but the calculator part of the app needs work. While trying to figure a percentage, i get an error. 32+6.75%=error............... EDIT: The equation is NOT wrong. Try it on any other calculator and it works just fine. Your programming is wrong. Changing my rating now to 1 star.

  17. yaboi_beasty 1257-avatar

    yaboi_beasty 1257


    Bro this app is amazing.... The app is hidden by a calculator.... Yo there is this intruder selfish where when someone tries to open an app and inputs the wrong pass in to many times (the amount you set) it takes a picture of who was trying to go in your phone.... It's amazing... 5 stars

  18. john-paul melendez-avatar

    john-paul melendez


    The app when the pictures are moved into it are cut off and you don't see the full picture anymore. Almost as if the picture has been superimposed. please assist with this.

  19. Arcadias Valstrath-avatar

    Arcadias Valstrath


    I really do like the concept of this app, but the security is not working well. I somehow be able to access locked app through notification on lock screen (Samsung Galaxy Note 5). I'll rate 5 star once this is fixed.

  20. Avo Cado-avatar

    good in every aspect so far aside from when I open it, it flashes my last viewed before pulling up the unlock screen. edit: can be worked around by opening and closing app after use.

  21. Keith Pearson-avatar

    Adding photos to vault takes forever to scan before opening. No access to settings after initially installing. % key comes up error. maybe input passkey in first then have option to press either % for settings or = to open. requiring draw over access before use. uninstalled.

  22. rahool raj-avatar

    Nice app and features. kindly include one more option to relock app on screen timeout/phone lock. thanks.

  23. Dan F-avatar

    needs work. put 2 apps in the lock and tried to add a 3rd and blocked me out of all 3. keeps going back to the calculators lock home page. after i remove the 3rd app from the lock list it works correctly.

  24. Surge-avatar

    The best photo vault i have ever used. But I sometimes can not add new photos. Other than that this app is perfect.

  25. Joel D'souza-avatar

    The app is working well, thumbs up to the developer. The only thing i want is how to hide the notification of Applock that "Protection is on".

  26. samin sarwat-avatar

    The creater of the app is very helpful man he helped me with patience regarding the apps problem.New update is rolling out most probably.Keep up doing the good works.

  27. Juan Valdez-avatar

    I filled with quite a bit of photos and folder will no longer open, other than that the app is quite good, haven't been able to open the folder for about two updates now sadly

  28. A Google user-avatar

    App with great potential. Runs with no problems so far on my LG G7. Couple of Suggestions: encryption and back up for user data.

  29. Gaming々zєяo々-avatar

    Nice however very low to display photo and no full photo display option..but i like it.

  31. Tony-avatar
