If the intent is to lock someone out who isn't tech savy, this is perfectly good. However, after my cat stole my yubikey and I had no way into my phone, I figured out all I had to do was reboot the phone and race the app. I managed to stop the service before it locked me out and then remove it. Additionally, there is no backup authentication method if you lose your key. This set me in panic mode when I lost the key, which lead to discovering how to bypass it.

While the app works like it should and allows unlocking with a NFC key I have found that against a very determined adversary it is entirely possible to override this app and gain access to a phone without the physical key. If someone can unlock your phone they can hail Google Assistant and "Open Settings" this app will fight but fast switching between the lock and settings screen allows you to eventually force stop the app and the phone is now unlocked.

Does not work on my Pixel 3 stock. (1) After authentication and it returns control over to the stock Google Pixel 3 home application, "Pixel Launcher", the launcher no longer works properly. The is NO WAY to swipe up and get to your app drawer. So there is no way to access your apps AT ALL unless you have dragged one to the desktop or you completely uninstall this app. (2) Tapping the home button on screen does not return to your home page of apps (3) My in-purchases are lost if I reinstall it

Too risky not to have a backup password and would work if it didn't share all your drop-down info before unlocking. Otherwise it's easy to install and a great app.

No updates in years! Installed on galaxy s8 plus. Running Android 9. it has caused my refresh rate to drop. My app icons appear one at a time slowly.

The app crushes everytime I click "Next" to choose it in the "Select a Home App" dialog, no matter how many times I re-install it or restart the phone...

works like advertized with my smart ring. my only issue is that the lock screen grants too much access to my phone.

Dan. G. Jun 14, 2021     

I opened the recent apps menu and clicked manage apps and was able to uninstall and gain access to the phone in seconds

Chr. K. Jun 19, 2019     

The only thing i would change is needing to purchase the back up password but a very good app very simple

Ale. R. Apr 14, 2020     

It works but I wish it could lock specific apps instead of whole phone

There is a chance if you phone turns off it forgets the device used to unlock it

Maybe this app doesn't work now cause Google stop supporting smart Lock for nfc

Works great with my xNT and Galaxy S9+

Cant use other unlocking methods except for nfc.

Joe. R. Aug 6, 2020     

Does not work well. Failing more time than sucess. Waste of time. Asking for money only.

Absolute Trash. Dont bother.

It has locked my tablet and I have just had to boot into safe mode to delete this app. I cannot unlock it because the dialog to select the program to handle NFC pops up and no matter what I do, I cannot get this infernal program to unlock my tablet. DO NOT use this if you have any other apps that work with or use NFC. (You cannot set a default app like you can with say, text files) DO NOT use this with a blank NFC card. (New tag dialog will block passing of information to the app)

App worked with the NFC card I had, however paid options are annoying, especially when all the paid options are preventative for getting permanently locked out of a device.

Ben. A. Apr 12, 2016     

Good, however alternate password feature only works every other time. I hope this gets improved especially as it is a paid feature.

Pal. Jul 24, 2018     

The app works well with my xNT implant. Though I dislike the amount of paid features and lack of personalization. Either way it works!

wik. May 11, 2018     

Amazing peice of software will definately be using with my soon to have nfc implant. Works fine with me just have to be careful regarding putting aeroplane mode on etc. Without the password addon. Very exited!

I like the idea of this app with Smart Unlock being removed, however when setting up this app it works, but as soon as you go back into the app and come back out the icon disappears and the featured is removed leaving device open for anyone to look at.

Dan. Jun 29, 2018     

Really cool for the first month or so then I got locked out and had to factory reset

Nei. A. H. Jun 8, 2021
