I downloaded it, and as soon as it shows the time, it crashes and shuts down.

### 3/5 — Fix please

*2015-08-24*

This app is great and looks great but it becomes a hassle when I try to use it by unlocking my phone, searching for the app, and clicking on it. I use it for work and it would be nice if it just showed up on my lock screen. Please fix, would appreciate and give a better rating.
