Best Calculator App! Free42 is by far my favorite calculator app. The HP42S has an ideal balance between ease of use and advanced capability, and this emulator is brilliant. Also, kudos to the author for continual improvements and responsive maintenance.
Amazingly good HP-42s emulator Same layout as the original. It even runs the same programs! (But it's much faster than the original). It would be nice if the key click were louder and used the speaker even when Bluetooth headset is connected.
Crashing fixed. Thank you!
Hp42 Very good calculator
Excellent! By far the most used app on my phone. Works just like the HP-42s sitting right next to me, which I no longer have to carry back and forth to the office.
Rolled back 8e, which was a disaster; it didn't fix the remaining black line issues, but it did cause crashes everywhere.
The previous fix for the thin-black-line problem didn't do the job on some devices. Here's another fix that should do a better job.
