  할아버지폴: Good apk for RPN lovers. I still have a 15c and the only difference I see is that I can't feel the keys because of the flat screen.

  ian goss: Having used HP calculators with RPN for 30 years and the 15C for 20 of those, I am very satisfied with this apk. It is even bigger on a smartphone than the original. Also use one on my smartphone.

  Joseph Olson: I still use my HP15C, but when I don't have it on me this apk is darn near like the true thing. The main difference is that there are no true buttons to push, but the haptic feedback is helpful in that regard. In addition, the size of the calculator display on my S4 is almost exactly the same size as the actual calculator.

  Dave Jacques: Works very much like my old 15C did with one exception. I have been unable to set my display to a default of just 2 decimal points. I will use fix 2 and all is ok until I shut the apk off; at which time it reverts back to the 4 decimal point default. Perhaps someone who knows how can pass it along to me.

  A Google user: A faithful reproduction of my favorite HP calculator. The only negative comment, and it is a little negative, is the apk sometimes shuts down without warning.

  Dory Sheldan: This is the best 15c mock up I've used. It is my regular calculator when I don't have my 15c.

  Victor Beazel: Good apk! The ten bucks I spent on this apk is insignificant in comparison to the cash I spent on the hardcopy. I still carry the original around in my backpack, but the only time it ever sees daylight is when my smartphone battery is dying. Having the HP15c with me everywhere is priceless. I even have the HP48G installed on my smartphone, but almost always use this instead.

  Bill Nickerson: I grew accustomed to RPN and the HP15C in grad school 30 years ago. It is good that the design of the calculator is still the best around and this tool implementation is a near excellent reply.

  Al Abnett: This is an outstanding apk. If you like RPN calculaters the 15C is one of the best, and I now use this one on my smartphone more than my true one. Thank you for creating it!

  A Google user: I'm very satisfied with this. Used a HP15C as my basic calculator for years. There is a minor bug on the T-mobile G2 in that the keyclick doesn't work. Still I was satisfied to pay $10 for this apk.
