  I use iHP48 as my default calculator app on my iPhone, and I do really like it, but it's a little irritating too, the main problem being that you have to be very slow and deliberate when typing out numbers. If you type numbers too fast it will likely drop a few. This isn't a problem most of the time, but I find it's an issue when I need to have multiple of the same digit (e.g. multiplying by 1000).

    I use this too. It had its fiddly moments, but it’s pros far outweigh its cons. It’s not my default calculator, I still use the stock one for that. But it’s my next stop when things get busier. The singular best benefit this has over an actual HP, for me, is a backlight. I find the original mostly too hard to read today. On the phone, it’s nice and bright and more than functional and useful.

  I’d guess that most people would be better served by a HP42 emulator for day to day calculations.

    Free42 for iOS is wonderful. I use it all the time and leave my real one at home, safe in a drawer.
