Comments on Touch RPN Calculator for Android

★★★★★ Frederic Vincent · Apr 11, 2025

Excellent app to access all flavors of the classic HP Voyager models of calculators. And the premium models switch button is a quite nice convenience feature. Last but not least, the exact same Voyager calculator apps are available on the desktop browser from the developer's website.

★★★★★ Greg S · Jul 31, 2021

OK... Updating my review back to 5 stars... The recent update wiped out my paid subscription and made ads appear, but I was able to restore it to add free by changing the flavors. It is a great RPN app just glad the vendor is still honoring their commitment.

★★★★★ Sergio Sperb · Jul 7, 2022

Had a little problem regarding the Premium version of the financial calculator but after a feedback from the support its working fine. Thank you!

★☆☆☆☆ Person Abc · Jul 30, 2026

Great app but breaches privacy through collecting advertising info. Would rather buy outright rather than constant selling my data to use it. Immediate uninstallation. All the great development rendered worthless by data breaching. I bought the official HP12c android app by the MORAVIA and worth it because it starts immediately, and doesn't try to "connect" online like this one does - instant start. Why does a simple calculator app need to connect online ?

★☆☆☆☆ Ian Bradley · Aug 14, 2021

New update has ads, although I Previously paid for ad free version. Tried changing the"flavor" back to premium but wants me to pay for it again. This is NOT what I originally purchased! Please fix, or refund the original purchase.

★☆☆☆☆ Michael Pearson · Jan 3, 2023

DO NOT REBUY. THEY CHARGE YOU AGAIN, DESPITE WHAT THEY TELL YOU! I have had the premium versions (financial and scientific) for years. Then the ads came back. Their website says to select purchase and that Googe will not charge you again. It took Google less than a minute to charge me (again). They are either cr... Unethical or incompetent.
