A simple and fun way to calculate numbers, Calc Basic is a reverse polish notation (RPN) based calculator with a built in stack navigator. Play with numbers and stack them like blocks.

Unique features include:

・ Stack Navigator -
A feature found in expensive engineering calculators, the navigator lets you see up to 5 values on the stack at once (for iPhone 5 and larger screens). It also allows you to scroll through the stack and set the roll and swap points with the up and down arrows.

・ Depth Indicator -
The depth indicator (displayed in green) shows how many total values are currently stored on the stack. Its range goes into the hundreds.

・ Sound -
The calculator has a button click sound which can be turned on and off (purple bar).

・ Saved Settings -
The settings for degrees/radians and the sound on/off values are stored for you so they do not have to be reset for every use.

Requires version IOS 7.0 or newer
