If I could write this without giving it any stars, I would oh, but I can't so I had to give it a 1! I'm using a fairly decent Chromebook oh, that should be more than capable of supporting this app, but every time I go to use it, it refuses to open! I tried uninstalling and reinstalling, but nothing! Guess I'll just have to do it the old-fashioned way and use the web browser! I need this app to be able to properly monitor my 12 year old son, so I'd appreciate it if you'd figure out what's wrong!
