App Profile: Calculator RPN

This is the best RPN calculator app I’ve ever used. The layout is clean, intuitive, and the buttons are clear and concise. The calculation steps/history immediately tells me if I’ve accidentally fat finger any keys while the “always on” feature (the phone stays on while the app is up) is a brilliant touch. This avoids the constant nuisance of logging into my phone every two minutes while I’m doing calculations. I use this handy piece of software nearly every day for work and home and it’s simply fantastic. My only wish is that it did unit conversions but it’s such a small gripe that it really should be a footnote because the rest of the app is that great. If you know how to use RPN, you won’t regret getting this calculator.

I have always used RPN calculators and could not use the standard x+y=z calculator that comes with the iPhone. Now I can use my iPhone for numbers again. Great product. Apple should have it as an option to their puny app.
