Apple's own calculator is a trash but this one is life saver if you use a lot of calculator , sound provided on keyboard is great just one problem the numbers are written really small making it hard to use it

Simply excellent

Tho the app is conceptually very sleek and functional, but it stopped working after 3-4 days, wouldnt open ,, and the screen would freeze on the developers icon.
Kindly remove this Bug.

The In-app purchase allows to do unit conversion. But Indian Rupee conversion is NOT possible.

Calcbot is one of the best App Store app. It needs a few updates. It does not start instantaneously on the new iPad. It takes a few seconds is to start. I hope it is rectified in the next update.

Excellent!
