User Reviews

Calc Pro is a feature-rich, all-in-one calculator with finance, graphing, scientific modes, unit conversion, and currency tools, with ongoing updates. However, stability problems, incomplete RPN support, pricey monetization with ads/paywalls, and UI/UX clarity concerns, plus occasional graph and calculation inaccuracies, are recurring themes in reviews.

I have been using this app for awhile and it is my go to app for currency conversions, volume and length calculations. Glad it is still being updated. Kudos.

Average - most calculators these days are essentially generic. The functions are available for all and if you’re going to charge $7.99 it’s important that you add something unusual and that you keep a running explanation of your functions. I find RPN to be so the I look for that and thought I saw it here. My bad. This is not well produced - it’s “10 functions” are not helpful - it does a lot of stuff but hard to find the list. I’m disappointed that I spent $7.99 as I should have known I could have gotten these functions for free. And I Didn’t get what I wanted which was RPN. Not bad but if you charge these days, it should be great. Thanks
