Has Features Beyond the Built-In Calculator
While iPhone 2.0 has a scientific calculator built in, you'll find it cannot do calculations in hexadecimal, or the less common octal or binary. Switch to Hex mode, and the statistical buttons change to logic operations --- functionality that you won't notice just from looking at the screen shot on the store. The calculator can also be switched into RPN mode, which many people still prefer from the days of their HP calculators. PCalc has many features that go well beyond what Apple provides, and if you happen to need those features it's well worth the $10. I wouldn't mind seeing some color coding of keys to make (for instance) the numbers stand out a bit more, but by and large this is a great app at a fair price.
Elegant, functional calculator
PCalc transforms your iPhone or iPod touch into the coolest scientific calculator ever. In vertical orientation it looks like an attractive standard calculator, albeit one with conversions (the A->B button), constants (the 42, representing the Ultimate Answer to Life, The Universe, and Everything), and more. But hold your device horizontally and it becomes a powerful scientific calculator, complete with RPN mode, hex, octal, and binary modes, and a simulated paper tape for tracking calculations as you go.
Most impressive is that typing on the keys of the PCalc keyboard is exactly the same as typing on the iPhone keyboard, right down to the animation when you press a key. That’s not an easy task—it’s all done with custom code written by PCalc's programmer.
pcalc review
I suffer from a heavy HP RPN addiction and PCalc fills the bill for me. The keys enlarge when you approach them like the standard iPhone keyboard giving it, with sound feedback, the right "feel"
Getting an interface on the iPhone is tough. You have to figure out the real estate - what is thrown away. This is a pretty good collection. A few minor quibbles, but I have to remind myself that this is my phone and the author has indicated a new version on the way.
Clearly one of the best iPhone apps so far!
