### 4/5 — Not bad

*2011-05-13*

I needed an app to tell me how many hours & minutes between one date, hh mm and another date, hh mm.  This works just fine for that.  I then need to add X hours and minutes to a date, hh mm.  This app does that fine as well.  The description of the app doesn't make it clear, but you can subtract dates/times as easily as add.  It's quick and easy.  I'd give it 5-stars if it had more features (like multiply/divide time and the ability to turn on/off dst changes).  I was very hesitant to spend the money without reading anyone's review, but I'm glad I did.  Been looking for this type of app for a long time.
