I was unpleasantly reminded of why I uninstalled this app a couple of years ago. After installing this app again, my phone will not send me any notifications for calendar events, text messages, or incoming emails. Absolutely no notifications, whatsoever! I was hoping by now, these issues would've been resolved with this app. That's obviously not the case though, as my recent experience proves. After uninstalling this app, all of my notifications work just fine! Install this app at your own risk!

Hi Raymond, thanks for using AppLock. AppLock doesn't affect the normal function of the phone and the running of other apps, there should be some misunderstanding. Please try to use AppLock for more time and send us feedback, thanks.

I'll give a 2 for now.. Haven't really used it. Just during setup, there are far too many ads. Some very intrusive and long. I will most likely delete the app for this reason. Edit, that was completely ridiculous. If you want people to use the app, at least limit ads for a day so it can be reasonably set up and used. I'd give less than a star if I could....
