Best calculator app on the iPad.

iPad doesn't have a bundled calculator app, so this is perfect.

Just the best.

Love this app. It is simple to use, clear graphics, great big calculator sound and you can see what you have entered scrolling across the top.

Good functions but slow start up.

This app has all the functions I want but takes bout 10+sec to start on my iPhone 4S. Prob not gonna use this Calc app until they improve on the start up speed.

Great app!

New landscape mode is a big improvement. Developer very responsive to suggestions for improvement.
