Great RPN Calculator 😀
Plus42 combines all the great features and usability of the HP42s and a.o. the units/units conversion and built-in TVM app. from HP48. The only thing I miss so far are the physical constants from the HP48.

Thank you so much for all the work you’ve done with this fantastic implementation of an advanced calculator. /Friedrich
In college I was an HP41C user. Once in my first engineering job I switched to the HP42S which has served me well over my 30+ year career. Once iPhones became a thing, I loaded Thomas’s Free42 and have been using that for a couple decades. I still have a real 42S on my desk for daily use. I recently purchased an HP Prime which is a lovely calculator but it’s just not completely comfortable to use. Switching to Thomas’s Plus42 feels really comfortable and adds lots of lovely features. I will likely purchase a SwissMicro DM42 to be used as my daily desk calc so that my phone app and physical desk calc are similar. That would send the 42S to the vintage calc cabinet. Honestly having this on my phone is massively so functional it’s hard to justify even owning a physical calc but there are times at the desk when it’s nice to grab the physical unit with tactile keys that can’t be interrupted with alerts :-). This is a beautiful upgrade to the free42. Thanks Thomas!
When using on iPad, the app occupies the whole screen. Currently it does not support multitasking. But it would great to share the screen with other apps (side or floating window).
Thomas has done an outstanding job on this app! It is not only the most beautiful calculator app out there, but it’s also the most powerful and functional of any of the HP inspired calculator app. The graphics are outstanding and the “extras” that were added in addition to the 42s standard makes the app even more appealing. If you know how to use a RPN calculator, this IS the one to have and use. If you don’t know how to use a RPN calculator, learn how and buy this. I always carry my phone, but rarely my physical DM42 or “real” 42s. You won’t regret getting this app. Congratulations Thomas for all the work you have done over the years relating to the 42. You should be proud.
With some programming, this can replace both of my units conversion and finance calculators apps. It is that powerful. I hope - and still have not figured out - we could use and call the TVM variables (PMT, FV, etc) in our custom programs, rather than duplicate the already available functions.
This calculator is the one I use first. It's powerfull, excellently done and works allways as expected. Also, it's well maintained. I wish all apps were made with this quality level.
Have been using Free42 for years but Plus42 is Free42 on steroids. The new features like Dir and Eqn are great enhancements. Many thanks for to this developer for all his efforts.
I have been using free42 for long time and I am glad you are offering a premium version and I can contribute to the developer of a great app.
I own multiple copies of the HP 42S, the DM42, but unlike those machines, my iPhone is always in my pocket. I have completely uninstalled the default calculator app and use the Free42 application quite heavily. I was really glad to see an upgrade with a bigger screen, so that I have something that’s close to the DM42 in my pocket at all times. This, I tell my students, is the best calculator ever made by man or beast. Thanks, Thomas!
