Why is the app free?
There are a lot of calculators in the app store. Paribus is way better, so we make it free for you to try. Most of the unique features are enabled without purchase.
How do you make money?
Some of the power features of Paribus PRO are only available with the single in-app purchase to upgrade. These include:
  • Spreadsheet mode
  • Quick tally mode
  • Advanced math library functions
  • Side by side versions
  • Saving named sessions
How do I enter a closed parenthesis?
Long-tap on the () key. It will enter a closed parenthesis instead of open parenthesis.
How do change the currency?
