This HP-15C work just like the original except when running intensive program no screen flashing while waiting for program to run this one just give you a blank screen. When conpute for a complicated integral the app crash and close then ask if you want to reopen again.
I have a 15C from 1984, an anniversary edition from 2011, and now this one. All work great! Now if Hewlett-Packard could only make their computers and software with the same high quality and robustness as their voyager series calculators...
Works better than my original HP15C. I am not disappointed. It is worth it since the limited edition HP15C are not affordable.
Thanks to the latest update it's now displaying properly on the Pixel XL. Thanks for getting this fixed!
Just like having my trusty HP 15C with me. Exact same functionality.
Sweet Memories... and So Convenient! This beautiful app brought back so many sweet memories from my college years and career as an engineer. Still have the original calculator in perfect working condition after 31 years, but so convenient to have the Android one in my pocket wherever I go! Thanks HP! EDIT: After using it for some time, one thing I wish it had would be the possibility to save and load programs to and from a separate file. This would turn this app into a real gem.
Addresses display issues seen with Android 7 on some devices.
Excellent scientific calculator with expressions, fractions, repeating decimals.
