Black Band

I have the same problem as rlcodyjr, a black band often appears across the screen where it makes it impossible the numbers. Otherwise great app. Best scientific calculator on iPhone.

FREE and Effecient

This is a good replacement for the calculator installed on the iPhone/iTouch. I have it installed on my iPad Mini too and have used it a lot for Math, Chemistry, Physics, and Accounting. Love the Clacky sound effect when pressing digits and shortcuts to inverses.

5⭐️'s because of its performance and free distribution. It does not crash. This app does not endorse extra money to remove ads or access all its functions. It is made fair and love this calculator.
