At first sight works, but if restart my phone ad try opening the "locked" app, it allows it and can use it for a minute (or so) , till App Lock wakes up and asks me to put pass. Also at the same time after restart, i can uninstall the App Lock. So, not safe. To the developer: Perhaps make the app lighter to start up faster?...

I've been using this about 10 days but it doesn't lock all the apps I've selected, sometimes it lets the app open & run for several minutes before it shows the unlock screen, and sometimes it wants me to unlock the app again when I exit the app. looking for a replacement, then will uninstall.
