Reviews From google play store

Awesome! Could you please tell me what is different about the Pro version, apart from no ads? Great app this is for my tablet. I don't need it on my phones, as l have Square Home Launcher on these, which does what this does. I don't like it on my tablet, however, so, this is just what l was looking for. Definitely 5 stars! 😎 Thanks for your response. I shall probably purchase it for my tablet!

It works as described! My phone doesn't have finger scanner. This app helps a lot to conserve my phone power switch. I don't have to press it anymore every time I need to screen lock and wake up my phone. Thanks so much!

Good job Dev! By customising this to access the power, volume and screen brightness controls from the floating button (long press), the physical power and volume rocker switches are not required. Ads are unobtrusive. Reliable. Thanks.

Does not work on stylo 5. Has ads it insists that I click before I can continue. Options are explained in broken English. When you try to actually lock your screen, it instead just shuts off your phone. Tried it several times.

So far so good. But sometimes it takes 5 seconds to lock (even when i set immediate in all option). Maybe because of compatibility with android 10 issue?

Worked great for a couple of days but now it immediately unlocks phone after locking. Re installed but it's doing the same again. How can I fix it?

excellent application. Saves a lot of wear and tear on your home button plus it enables you to open up to other applications from the icon

I have been testing out screen lock apps and this one from Simi Studio is the 5th. There is a paid version but you only see it when you read thru their description in the store. It is working well so far and I don't have plans of uninstalling anytime soon. I have the app on all the phones at home that need it.

Great app. Works w/ fingerprint sensor; before needs to enable the 'fix' option to work, but developer kept improving the app so that it works seemlessly. Unlike other screen locker app, we don't need to wait for a few seconds after locking to be able to switch the device back on again. I like the new update of long-pressing home button to lock, i can choose to remove the floating icon and keep my screen clean. Thank you developer

This app doesn't do what I was looking for since the lock time takes so long on my device, even when set to immediately. My problem is that the app will not uninstall. Something in it is keeping me from being able to uninstall it and that is pretty infuriating.

These location services must be turned on and available to your device for the app to use them. Apps may use this to determine approximately where you are.

precise location (GPS and network-based)
Allows the app to get your precise location using the Global Positioning System (GPS) or network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine where you are, and may consume additional battery power.
