CalcFast Is Efficient, Good Looking

CalcFast is simple to use and works great. The calculator looks good on both my iPad and iPhone. For me this calculator is much nicer than the stock calculator supplied with the iPhone. My thanks to the developer for an excellent app that is easy to use. Job well done!

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.

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.
