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.

★★★★★ 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!

★★★★★ 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.

Careful with this seller. He removed the previous premium version, which I bought and re-added it to Google Play under a different name (Same app I believe) to get people to buy it again. Looks like he said it wasn't his fault, but I did not receive a refund to buy it again. I bought a different version.

★☆☆☆☆ 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.

★☆☆☆☆ Scott Dysart · Jan 8, 2022

If you are on a much older version you like, do not upgrade. I inadvertently updated this once outstanding, polished app to the advertising layden monstrosity it has become. If taking values from another app, you are presented with an unclosable ad for each number entered. I like that developers can monetize their work product but seriously, when you have to be subjected to multiple full screen ads and play find the tiny close hot spot just to do a single calculation it has gone too far.
