    Best..so far!! A good alternative to preserve your power button's life cycle. This is the first lock screen app/button that allows you to unlock with fingerprint..and i also like the neon blue color of the icon too..the previous ones I've tried will ask for unlocking code everytime you locked your phone by tapping on the "lock screen" button, so they were completely useless. This app is the best, so far and uses almost no space on your storage unit.

  2. hariom-avatar



    Hi developer... The bad thing is that after I use it to lock the screen, the fingerprint input is not taken, I have to re-enter the phone password to unlock screen. "The fingerprint input is not taken and I have to enter my password." ... Please allow so that after locking, one can easily unlock with the help of fingerprint.

  3. dontwakemeup-avatar



    I love it but it randomly stops working from time to time and I have to reinstall it to have it working again. 🤔

    Very easy..... Just 1 tap for screen off. Dont get hesitate to use this app. Its very simple. Only 1 touch in the icon your screen will get off .... Activate the app for using Thank____You

    It would have been better if it doesn't require a pin code to unlock after using fingerprint unlock, it's so annoying that it does that EVERY SINGLE TIME! It's senseless. Uninstalling now.

  6. Jaswinder Singh-avatar

    Jaswinder Singh


    Works perfectly on my device. Only thing that can be improved is the app icon. Rather than a lock icon, a round power button icon could be much better.

    Nice app, easy to use & compatible with biometric unlock. But there is a bug causing Gboard tool icons to freeze & unable to customise when activated.

  18. Renatta Joseph-avatar

    Renatta Joseph


    Suspicious app.Why does this app need access to retrieve window content? What is the need to inspect the contents of the screen I am interacting with?

  19. James Ross-avatar

    James Ross


    best app ever, made a routine on google voice to open this app when or just say ok google open lock screen, and it locks perfectly and only takes the pin to unlock, which is great, i can still use my fingerprint until i give the command, dont have to worry about anyone using methods to get in with the fingerprint, its good security measure, but in certain situations i would rather know and require the pin, that way you know your civil rights wont be violated. Thank you for this app.

    Oleg Anishchenkov


    Uninstalled! Before starting the application you need to give permission to unlock some features in the setup program but the prompt screen appears only for a few seconds - you really can't read it. I started the application three times and still failed to understand what this application wanted me to do.

    Great idea of having such a useful app in a compact size with no advertisement and even the app do not starts , just acts like a widget and os great to use. On my other device with Android jellybean it is having a little trouble as the lock screen sound comes twice but although a good app to use.👍👍

    Bharathi Raja K


    Best app in the play store for Android pie with finger print enabled. Tried many apps this one works flawless. Very light weight and no battery consumption. Widget can be added with customized logo colours and even invisible one would be a cool add-on.

  29. mohan kasi-avatar

    mohan kasi


    It's very simple and light but only locks the phone and doesn't blank the screen. Pressing the phone's inbuilt button does both. It's still better than all the other advert filled apps.

    When enabling face unlock on S10, after locking the phone using this app, the screen immediately turned on and scans for my face! It would be great if I can lock the phone without that problem

  37. Venkata Raju-avatar

    Venkata Raju


    Seem to work fine. 'Please enter passcode to enable finger print' message on Unlock screen is a bit misleading (my phone has passcode enabled, no finger print).

    For some reason, once locked, it also disables finger print. I don't want to enter pin everytime I want to unlock the device, otherwise the fingerprint becomes pointless right.
