As close as you can get to an actual 15c without a physical keyboard. Even the dimensions are the same (Galaxy S4 Active) as my HP. For $10 it is worth it if RPN is your thing. The only change I can ask for is to make the font on the virtual keys bigger or bolder- they're tough to read especially with the screen brightness anything less than 100%. Great app otherwise!
Works OK. Not quite the same as the HP coded one for iPhone:but also not $40 Australian dollars. Well worth the money for people who have used a real calculator - not one of those useless things that has an equals button
As close as you'll get to the real thing I still use my HP15C, but when I don't have it on me this app is darn near like the real thing. The main difference is that there are no real 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.
The old familiar Having used HP calculators with RPN for 30 years and the 15C for 20 of those, I am very pleased with this app. It is even bigger on a tablet than the original. Also use one on my phone.
15C Great App 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 fine until I shut the app off; at which time it reverts back to the 4 decimal point default. Perhaps someone who knows how can pass it along to me.
Great HP 15C calculator The best 15C emulator I've have seen and used. Once you have tried RPN for real you're hooked for life!.. ☺ The only thing I miss is the tactile feedback my trusty old (30+ years) HP 15C gives me... ☺
minor bug fix and performance optimization
