I mainly use this to lock apps, BUT it is getting to the point that it informs me that App Lock is not enabled on a weekly frequency. if any one stole my phone it would be a matter of days before App Lock was disabled, it's getting pointless to have this app at all. Previous review - I think I turned this feature off. Too much bloat, which I find annoying, such as clearing the clipboard, just clear it we don't need the stupid time wasting graphic, it should be instant.

Hey Ron, thanks for taking your time. The app lock feature certainly should not be automatically swithcing off after a week. If you feel it does, please reach out via the app's Menu → Help & support → Avast direct support, and let our support team assist you. Thanks, David*Avast

Had the app for years, fine until recently. Good features like the checking for stolen passwords, data breaches etc. but over the course of the last few years more and more features are locked behind a paywall for Premium. In the past few days, I'd allowed the app additional Permissions & Notifications too but today I've been infuriated by the fact that EVERY time I unlock my phone screen, it's on the the Google Pay screen attempting to take £29.99 for Premium. Unhappy, Uninstalled. Be careful.

Steve, we’re constantly running various experiments in order to optimize the monetization model to secure enough funds for supporting the development of the app providing key functionality for free. Thanks for understanding. David*Avast

This is really very good security for you and your phone, if the screen changes because you selected a different routine or app it locks the screen, this means that remote access to your phone by bad actors will be more difficult, there is an app lock that facilitates this, ( look for this in "explore" ), and you can use a full time VPN so hackers cannot see back down the line to you, this is excellent, everything I need!!
