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.
Just like the good ol days of using rpn calculators. Personally preferred the 11c from Hewlett Packard but this program ticks all the boxes
Free 42 is fantastic! Best RPN calculator app by a significant margin.
Just like the original Had the 42 in college, this is great. A trip down memory lane in a familiar UI. Too bad I don't do real engineering anymore!
Good old rpn I don't like that the number stack is limited to 3. Otherwise it is a good program.
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.
