This app is completely free, no ads or extra bits to buy. I love this calculator and I like to share.
What’s New
Version 1.1
This app has been updated by Apple to display the Apple Watch app icon.
Updated 64 bit build that will survive long past the next iOS update.
Also, the calculator display now scales correctly for all iPhone screen sizes.
The name of the app has been changed to "Retro 15C". It's still free and always will be.
Thank you for your support!
Ratings and Reviews
Superb
Early on in my career in 1981 I got an 11C and love(d) it. It still works perfectly and I will sometimes use it even if most work is now on PC. The looks and workings of the 15C are virtually identical and I love having it on my phone. Thanks so much for sharing!
Geweldig
Deze rekenmachine waarmee ik in mijn studietijd en tijdens mijn loopbaan talloze berekeningen heb uitgevoerd behoort tot de topklasse. Geweldig dat deze simulator nu beschikbaar is voor de iPhone en iPad.
Great job!
I really love it, even though I still have my original HP15c it is great to have it in my pocket all the time...
I just wish that there was proper key click - that would make using it even more practical
