You've been there... Running the numbers on the next business decision when the math gets too complicated to do in your head, there are too many variables to track, or you want to compare results from several assumptions. Handheld calculators are cumbersome, and spreadsheets need the laptop you left in the office.

Paribus was made to get everyday business math done with the iPhone that's always in your pocket.

For that quick conversation or hallway meeting, Paribus lets you type like you talk and get back instant results.

Run down various scenarios with multiple cells. Break up the assumptions so you can quickly change a value and see the result. Then share it with your colleagues and get back to work.
