Very nice App.

I have been using it for a few weeks now. The feature I most like is the calculations tape which is fabulous. The reason for 4 star instead of 5 star is that the developer has not contacted me back in reply to my email.

Calc Fast simplicity hits all 5 stars

Exactly what I was looking for in my calc app. Records are kept or deleted in a simple yet secure fashion. Historical calculations are simply to find. Very basic but it seems to calculate my larger commission amounts just fine.
