The portrait view is NOT an hp 12C calculator! This is a rip-off since other apps i use are portrait mode and I use the calculator in the same orientation. It is a hassle to have to constantly reorient my phone for this app. I'm heading back to a 12C knockoff that knows how to provide users an intelligent portrait implementation of the 12C!
Doesn't work on Android anymore. Only simple calculator.
This calculator is very fun & easy to use. Took some time to get used to this calculator. I used it all the time for math class at school. All I need to do is tap a number + tap enter + tap a diffrent or same number + operation (+ × ÷ or -) for math. Would love to own the real HP 12C someday just because it was that fun to use.
Excellent. Looks good and works well
I have 3 HP12C Calculators. Bought my first one in 1983, still works, and change batteries every 3 to 5 years.
Very sophisticated program
11/27/20 I followed the recommendations below and reset and now my HP works great again!
Why in the actual **** is my calculator app uploading data off of my phone on the daily when I don't even open the app period?
It doesn't fill my screen. It doesn't default to wide view like the knock off does. It doesn't have keys that vibrate so you know you touched keys
Stopped working, zero support, very disappointed, a great app
