Ridiculously good app, worth far more than the price

My previous review seems to have disappeared, so let me update it. If your brain is wired to use RPN (from HP calculator days), you should definitely buy this. Full stop. Ive bought every RPN calculator in the App Store, and this is the best.

Even if you dont use RPN, you should almost certainly buy this. Flexible, powerful; configurable, pretty to look at (unlike some, I love the new icon), constantly updated to keep pace with new Apple features... if you care enough about calculators to be reading this review, youll like PCalc. Buy it!
