Froze almost immediately

When I first opened the app it asked if I wanted to recover memory. The yes/no buttons are unresponsive

great app ... but a bug with bottom row of keys

GregWoodward on

United States

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.

Doesn’t work anymore

Buggy

Jose_PR on

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.

Super slow

Slow to load up and register key presses. Makes this annoying to use as a calculator.

New version introduces lag

NinjaRunningWild on

United States

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*.

Good, but with a few problems

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.

No Longer Working

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.

Try iHP48

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.

No longer works

Stopped working recently. I’m assuming with the newest iOS, it stopped.
