Glad to see a good implementation of this. For a CS engineer like myself, it is very useful. My only complaint is that the scrolling keys do not move digit-by-digit, but word-by-word. This should probably be addressed. See pages 33-34 of HP-16C Owners Handbook for what I'm referencing. Thanks. Edit 02/05/2017: Thanks for the correction! Good work!
The closest emulator to the 16C calculator that I've owned since the early 80s. Well done and well worth the small price.
Awesome～ Totally great. Thanks for keeping out the ads and splash ad screen.
Great implementation App works very well. Great copy of a great calculator.
New Settings menu format.
Hardware keyboard support. Check the app's home page to learn the keybindings.
Excellent scientific calculator with expressions, fractions, repeating decimals.
