Customer Reviews

Best rpn out there

As stated in the title, best calculator app. It's extremely powerful yet even a novice can use it. All in all, I would highly recommend. The developer is very responsive and has addressed all of my questions.

There is a hidden help menu under options. Awesome feature but many may not notice it.

Features that I really like:
As a professional, I'm required to do fast number crunching. Love the ability to whip open the app and punch away.
Black theme with blue font looks very professional and easy on the eyes.
Ability to set dec or eng or fin by simple up down swipes. Also, ability to set decimal places by simple left right swipe on display panel.

Features I would love to see in the long run:
Ability to email directly from app in a beautiful format like Digits or Soulver.

Bottom line: I would pay $5 for this. It's the scientific version of pcalc and does many things far better.
