I use an HP48GX daily for my engineering work, and have lots of customization - KEYMAN, UNITMAN, lots of applications loaded, etc. This emulator allows you to load up any of these customizations very easily - more easily than on the real hardware in fact. I do manage to crash it frequently when messing around with the applications and configuration in various ports, but it usually restarts back within a couple of actions. Overall I’m super impressed with this and use it all the time when I don’t have the real thing at hand. ### 4/5 — My go to iPhone calculator *2026-01-21, version 1.9* Well developed calculator, works just like my old HP48 in school. ### 3/5 — Good but constantly crashes *2026-01-09, version 1.9* Love it, except for the fact that it constantly crashes on my iPhone 12 Pro Max. Doesn’t crash for my coworker, don’t know what sort of phone she has… ### 4/5 — Solid Emulation, but No Keyboard Support *2025-12-26, version 1.9* Really great port of the emulator to MacOS. However, there is zero support for the keyboard. The basics should be mapped like the letters, numbers, and arrow keys at a minimum. For bonus, map the ‘~’ to alpha key, +,-,*,/, ‘on’ to ‘esc’, ‘<-‘ to left shift, ‘->’ to right shift, and ‘backspace’ to ‘delete’ key. ### 5/5 — Best calculator *2025-12-04, version 1.9* Solid app. If you are an engineer, don’t need to look for something else. ### 5/5 — Using daily *2025-10-29, version 1.9* Loving this app, using it daily! Nostalgic, but more importantly also faster for me than any other calc app. ### 1/5 — App constantly crashes *2025-10-11, version 1.9* While this emulator is by far the best HP48G/GX emulator for iOS I’ve ever used, *while it’s working*, the reason for my rating is that *the app constantly crashes randomly.* This is on an iPhone 12 Pro Max running iOS version 18.7.1. If the app didn’t crash, I’d definitely give it five stars. ### 5/5 — Love it *2025-10-03, version 1.9* Just like my HP48 that now I can leave at home. ### 3/5 — Ideas to improve *2025-09-15, version 1.9* Fix the crash Remove the ugly keyboard Remove the on/off button ### 5/5 — The very best! *2025-08-16, version 1.9* after a couple of years of use, switching from my 48g+ to the app, I can say is really fantastic! thank you a lot for your work of love! ## Frequently asked questions about iHP48 ### What does iHP48 do? iHP48 is a mobile application that revives the classic HP48 calculator experience.
