Centulator is now FREE! No advertisements, no nag screens, no "pro version" to upgrade to.

Centulator makes percentage calculations. Forget trying to remember the variety of formulas you need to calculate percentages, Centulator does it for you, quickly and easily.

This is a complete rebuild of Centulator, using Apple's brand new programming language (Swift) and with a completely new interface to better suit the look of iOS8.

The following calculations are included:

What is A percent of B

What is A as a percentage of B

Increase A by B percent

Decrease A by B percent

A less 17.5% tax

A plus 17.5% tax

A less 20% tax

A plus 20% tax

Percentage difference between A and B

The result of your calculation can be copied and pasted into another app on your device at the touch of a button.

What's New in Version 1.6

Completely rebuilt in Swift
Brand new interface
Static orientation (portrait)
