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.
It Just Works Very clean-looking app, better aesthetics and performance than other ones on the store. It has a basic version of the calculator when in portrait mode, and switches to the full calculator when in landscape. Very small install, HP did a good job with this. A bit pricey for an Android app, but cheaper than buying the real thing.
Even better than the original, which I have still. Everything I have tried, including programming, works just as it should. But on my 7" tablet it is bigger than ever before ! The emulation of the front of the device is truly well done, it looks like a photograph... wait, it may be a photo.... update: under 15c logo, first press brings up 'settings' and I chose fix landscape, afterwards settings never reappears which is silly.
Just like the real thing but ... The key click noise is terrible. At least there is an option to turn off the sound but it would be nice to have audible feedback.
