Customer Reviews


Display flashes after program execution.

Also sometimes hard to tell what key you've hit. Making the key 'light up' or magnify like text input on the iPhone would make life easier. The now-unavailable sci 15c app was less buggy and easier to use. I am glad my 'real' 15c and 15c LE are better than the app.

HP 15C Limited Edition

After installing app I was surprised that there was no trig or programming but the calculator switches to all features mode when rotated from portrait to landscape. The manual displays nicely too. I was puzzled by limited edition and discovered HP has reissued the 15C hardware recently and is available for ordering as of June 2012.

Nice but update needed

Apple warns that this app is slowing down our iPhones and needs an update. It's been 4 years and needs software updates. Please HP! Thanks then more stars.
