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!
Thank for the update now work on my S7 Edge
My Favorite 15c My 15c gave up the ghost after 31 years. It got me through grad school and a long career. I've tried other rpn calculators. I don't like them, and no way I can afford the rare 15c's that still exist. So pleased this great hp app brought my old friend back to me. Thanks!
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.
Love it, perfect emulation This looks like the real thing as well as emulating it. There are many HP calculator emulators around, but the graphics always lets them down. This is perfect. Plus there's a practical portrait mode view. BUG: Make it run a program in a loop, rotate to portrait, then run another app. If you switch back to it, it won't switch back to landscape mode and slows the phone down considerably.
