This app is fine as a protection from kids or from accidental app use by elderly people, for example. It's not a real security measure, though, because it doesn't actually block the app completely. It only covers the screen over the app. But it's not perfect, so the actual app screen can often be seen and used for a few seconds before it's covered. For example, I tried to use this app with the Authenticator app. But most of the time I can actually see and remember the one-time password in Authenticator before AppLock covers the screen.

I've used this app for years if not for up to a decade! It's been nothing short of excellent in locking my apps & especially gallery (pics & vids). Highly recommended, a little drawback is the ads tho which can be a little hectic and sometimes unskipable requiring you to exit & reopen. Although it's a fair price to pay for it's performance and being free to use

been using this app for 9+ years. lately the ads have gotten out of control. It literally takes over my phone and I can not open any apps, including the unlocked ones until I watch a full ad. liability especially if I need to pull up something urgent
