User Reviews

RpnCalc is highly praised as the best Android RPN calculator with a retro HP-like feel. Users love its accurate RPN workflow, design, and portability. It's lightweight and reliable, making it a favorite for engineers and HP enthusiasts. Reported drawbacks include a menu-opening bug that appears after restart on several devices and inconsistent clear button behavior (sometimes clearing all registers or acting as AC). Some HP-41 features are not fully supported, and a few users want better Android version compatibility. Overall, it's a top pick with a few UX issues to fix.

Pros

Excellent RPN calculator with a nostalgic HP-style interface; widely regarded as the best RPN option on Android.
Extremely easy to use and efficient for RPN workflows; strong nostalgia appeal for HP users.
Lightweight, satisfying to use, and highly portable; a go-to calculator on the go.
Loved by power users; considered a favorite or best RPN calculator on Android.

Cons

Menu access bug that lets the menu open only once per app run on multiple devices.
Clear button sometimes behaves inconsistently (clears all registers or acts like AC).
Not all HP-41 features are fully supported and some quirks (e.g., Last-x behavior) exist.
