i48

很强大的科学计算器，还不太会用，只掌握了其1%的功能

very good!!!

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

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

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.

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

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*.

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.

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.
