The base app that comes with the phone is flawed and unreliable. Timers and alarms don't always go off, which is an extremely important feature to make sure is right with an app like this. I've had this issue access to devices and seeing the other reviewers, I'm not alone in the problem. Something as simple as a 20 minute timer won't go off reliably. There aren't any "missed alarm" notifications for when the alarms don't ring. Nothing but disappointment.
