User Reviews

Touch RPN Calculator is a faithful HP calculator substitute with accurate RPN and broad flavor support, plus useful features like program/memory save-restore and an ad-free paid option. Recurrent drawbacks are intrusive ads, update resets to an ad-supported mode, plus occasional UI glitches and some licensing concerns. Overall, it’s reliable and true to the originals, with good value in the paid version but room for polish.

Pros

Faithful recreation of HP calculators (12C/11C/Voyager) with accurate RPN.
Rich feature set like saving/restoring programs/memory, support for multiple HP flavors, and convenient premium model switch.
Reliable, high-quality simulation that serves as a strong replacement for physical HP calculators.
Ad-free option via paid version provides good value for a smoother experience.
Cross-device availability, including a desktop/web version of the Voyager models from the developer.

Cons

Intrusive ads are a common complaint, including loud or persistent banners and data-collection concerns.
Updates often reset to the ad-supported financial version, forgetting the user’s preferred flavor and re-enabling ads.
UI/UX issues such as screen orientation problems and a low-resolution interface.
Licensing/purchase concerns about the seller’s handling of premium versions and refunds.

Recent reviews

I've used for years. It would be nice to be able to align the premium version to the bottom of the screen when in portrait mode unstretched for easier one-handed operation. Stretch Display doesn't really help this. Galaxy S26U. Edit: Dev response will alleviate my issue. Thanks!

Good calculator, the only really annoying issue is that it randomly switches to the i11 version with ads about once per year. Couldn't you change it so that when it loses the settings, it switches to an ad free one if the user bought one? I only bought i15, which is the only calculator I use, so this would fix the issue for me.
