The skins are great, and it’s really easy to set up. The haptic feedback and responsiveness of the input are really nice. But for the last year or so, I’ve been having a problem where it just freezes and becomes unresponsive. It usually happens when I switch to another app and back. If I reset the CPU, it will sometimes come back, but usually it doesn’t. Other times, the input will slow to a crawl, only accepting inputs every 2 seconds. The input will get buffered and will enter automatically at this really slow rate. While it functions, it’s not usable. I really love this app, but it’s just become unusable. I’ve had to bring my real HP48 out of storage, but it’s hard having lost the portability and availability of having my HP everywhere I go. ### 4/5 — Library files? *2024-01-10, version 1.15* Is there a library out there that emulates the old Sparcom add ins to the HP68GX? ### 2/5 — Needs an update *2023-11-21, version 1.15* I would have given this 4 stars as I loved my HP48G, but the app has become more and more glitchy with subsequent iOS updates (ipad v16). Please help me change my rating! ### 2/5 — Super slow *2022-06-05, version 1.15* Slow to load up and register key presses. Makes this annoying to use as a calculator. ### 2/5 — New version introduces lag *2022-04-04, version 1.15* Don't update if you haven't already. This new version introduces SIGNIFICANT lag into key input, sometimes just ignoring input altogether, other times sending the last 3 commands through all at once. This makes it unusable. Also, hitting the drop button somehow advances the time... This is the opposite of an update. This is a *downgrade*. ### 2/5 — Good, but with a few problems *2021-11-14, version 1.15* I love how it looks just like the old HP48! But sometimes, especially when first opening the app, it doesn’t register buttons that are pushed. Also, unlike some other HP48 emulator apps, it doesn’t offer any haptic feedback to help you to be sure you really pressed a button. ### 2/5 — No Longer Working *2021-10-12, version 1.15* I’ve had this app for years and it has been working perfectly fine up until your last “fix”. Now some of the keys won’t work. Like so many others I’ve uninstalled/reinstalled, several times, but unfortunately the problem remains. ### 2/5 — Try iHP48 *2021-07-22, version 1.14* Like many other reviewers, I’ve been suffering with the button response problems on i48 for a long time. Recently the arrow keys stopped moving the cursor one character or row at a time, instead deleting the entire entry, going to the top/bottom of the stack, or erratically moving around within menus. I tried uninstalling & reinstalling but that didn’t help. This new problem took i48 from just annoying for basic functions to pretty much useless. I happened to find iHP48 in the App Store, and it seems to have been out for a few months now. So far so good with this replacement. ### 2/5 — Button press sensitivity *2021-04-06, version 1.14* The button sensitivity sucks on this app. It is very frustrating when you have to press the same button multiple times to get it to register. The lack of sensitivity means that many calculations end up wrong because a button press did not register. ### 4/5 — Reliable *2021-02-19, version 1.14* Thanks for the icon update! This calculator allowa for reliable and fast tiping unlike competing ones. ### 2/5 — broken *2021-02-02, version 1.14* Once an excellent copy of the hp48G, now no longer working. App and buttons completely unresponsive. ### 2/5 — Broken on IOS14. *2021-01-11, version 1.14* Does not work most of the time. ### 1/5 — Unresponsive on my ipad *2021-01-09, version 1.14* Sad ## Most critical reviews (10 lowest-rated) ### 1/5 — Needs Updating *2026-01-10, version 1.15* I loved this app, but it is not maintained and does not function under latest iOS. ### 1/5 — Buggy *2025-11-26, version 1.15* This thing crashes all the time. Don’t Panic ### 1/5 — Unusable now with latest iOS 18 updates *2025-04-28, version 1.15* Used to be great. Now constantly turns off about every 3-4 seconds. Totally unusable. ### 1/5 — Bad *2025-02-21, version 1.15* EDIT does not work on my i16 phone. Did work on my i12. Almost useless as is for me ### 1/5 — Froze almost immediately *2023-04-11, version 1.15* When I first opened the app it asked if I wanted to recover memory. The yes/no buttons are unresponsive ### 1/5 — Doesn’t work anymore *2022-12-11, version 1.15* Doesn’t work anymore ### 1/5 — Buggy *2022-09-30, version 1.15* I loved the original calculator. I love a version of the calculator on Android. I hate this one. I have to tab the buttons several times before it does the action. I have tried on 4 different iOS devices and the behavior is exactly the same. That makes it useless. Nice try, though. ### 1/5 — Used to be great *2022-05-10, version 1.15* I loved this app, but sadly it has stopped working on my iphone 13, SW 14.4.1. The interface freezes and becomes unresponsive or it starts acting like I'm pushing the "Off" button. and clears the screen over and over. ### 1/5 — No longer works *2021-06-26, version 1.14* Stopped working recently. I’m assuming with the newest iOS, it stopped. ### 1/5 — No longer works *2021-04-24, version 1.14* I used this one for years and loved it. Apparently it is no longer being updated and does not work with the latest iOS. ## Most praised reviews (10 highest-rated) ### 5/5 — Needs updating *2024-12-07, version 1.15* The only calculator I use on iPhone. Sometimes freezes or crashes, though, needs updating ### 5/5 — I love the app *2024-09-04, version 1.15* This app has been great since my actual 48GX broke, and I use it often. this is the reason I give it 5 stars. that being said, while it still works on my phone, it has stopped working on my computer, where the interface is stuck, and the problem is still present if I delete and redownload the app. ### 5/5 — amazing hp 48 emulator *2023-06-13, version 1.15* my real calculator has developed lcd rot so having this app available has been great. please keep up the great work. ### 5/5 — great app ... but a bug with bottom row of keys *2023-02-20, version 1.15* Perfect - preformed very well until i had to delete and reload. the bottom keys {0, . , spc, +} are now very flaky. verified it’s not my screen... any ideas? i won’t “upgrade” the iOS on my ‘20SE because i don’t feel like allowing apple to purposely degrade my battery. ### 5/5 — Awesome!! *2022-09-28, version 1.15* Awesome app. Just like the 48G I had in engineering. Been a bit glitchy lately… but I know the team will be fixing it. It’s honestly the best calculator app around :) ### 5/5 — Great calculator *2022-06-03, version 1.15* You made my day! I was looking for my old hp calculator and found this emulation for iOS. Same calculator I had at university. Feel like home again. ### 5/5 — Brilliant *2021-01-04, version 1.14* New update wasn’t working but I deleted the app and installed again and now works fine !!! ### 5/5 — Latest Update Rocks! *2021-01-03, version 1.14* Downloaded this originally so I wouldn’t have to carry my HP in my bag. It was harder to use and a little laggy with touch. This recent update fixed all or that and pretty much any complaint I had. In my case a legit replacement for my i48 when I’m not at my desk. Thank you for creating this and the recent update!! ### 5/5 — Works great *2021-01-03, version 1.14* Use it all the time, even more now that my real 48 finally died.👍 ### 5/5 — Thank you for making this app *2020-12-28, version 1.14* I am so grateful for this app, I don’t have to drag my calculator around with me. This app does everything that I need it to do. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
