Glad it is still being updated. Kudos. ### 3/5 — No RPN *2025-03-11* 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 ### 5/5 — R P N *2024-09-08, version 6.9.0* I learned how to use RPN on HP calculators. It’s the best wayvto fo math in my opinion. ### 5/5 — Merci et bravo !! *2023-03-20* Quelle joie de voir que les développeurs continuent de supporter ce que j'estime comme étant la meilleure application de calcul que je connaisse...! ### 5/5 — Wonder full calculator *2023-01-31* Been using this app since the ice age and can’t live without it. Best I have used! ### 1/5 — Waste of money *2021-10-26* I just paid $14.00 for this and it will not even boot, t really can’t afford to throw money away on junk so will certainly not buy from thiz developer again. Please refund ### 2/5 — Português *2021-08-24* A conversão para língua portuguesa é horrível. ### 4/5 — Impossible to Update for Currency Values *2021-02-14* I have enjoyed this app for years, until last week when I couldn’t get the date to reflect the current date. Today I went to the App Store and decided perhaps I needed to purchase a new version of the app .$7.99 vs what I believe was previously Free! Only to receive the exact same notice , “unable to connect” ... while I am connected to the Internet! Wi-Fi on my Apple XR. Now I’d like my Apple charge refunded ! Ever hopeful someone will contact me! precious Auntie ### 5/5 — Bon appli *2021-02-13* Bonjour, Problème sur votre application. Dès qu’on appuie sur une touche +*- tout s’efface donc appli inutilisable pour le moment. ### 4/5 — Was great now not working *2021-01-15* Since updating to the latest version of iOS this app no longer works. ## Frequently asked questions about Calc Pro ### What does Calc Pro do?
