  • Best Calculator I’ve Ever Used

    By gwmelchi
    I am a retired biochemist. I used a slide rule for the first 10 years of my career and then the finest HP calculators that were available until I retired. This PCalc is as good or better for my purposes than any other calculator I have ever owned. I use strictly RPN, and there are a couple of quirks that you have to get use to, e.g. you have to use the “swap” key when solving combinatorics with the built in combination and permutation keys, which is anti intuitive, but easy to get use to. Overall this is a really nice calculator and I can recommend it for most common math applications with no reservations.
  • I use this app every day

    By Thebanite
    I've used it since nearly the start. It does everything well and is customizable. The developer is great. Buy it!
  • I can’t get that last banana!

    By boboneill
    Yea, it’s a great calculator...no doubt. But I cannot get that last banana. I have tried traction mode...heck, all the modes...i’ve tried the chunky truck and the semi-racer car...but every time I jump, I OVER jump and miss the mark. I will try firing light at it...maybe I can get it that way....ok, I’ll try that... I am also highly suspect of that regular flight that passes over me...and the tiny train. I am convinced that I can somehow hit the plane with light (or maybe a 42??) and then I will be flying instead of driving. The dance continues... Update...I spoke too soon...I am now a helicopter pilot, so still lots to explore...
  • Worth every penny

    I was skeptical at first, but the more I use this massively featured calculator the better I like it. My compliments to the developer for an impressive app.
  • Chinese please

    I want to a Chinese edition.
  • Used to be great BUT...UPDATED 7/7/18

    By Dennismk
    Tech finally got back to me and suggested a reset that worked and restored everything back to normal...so revised back to 5 stars! Ever since iOS 11, whenever I attempt to download/operate it, all I get is a fragmented keyboard and multiple blank squares. Hoping one day it will get fixed.
  • Unbeatable

    By krag0th
    Simply the best calculator app for the Apple platform. It has everything I’ve needed, and it’s super easy to use.
  • It just works. Really.

    By WT9T
    PCalc has lots of features but no feature-brag: You can customize layout, appearance, behavior… to the point where any more would be satirical. What’s left after you have molded PCalc to the way you work is a calculator that does what you ask of it, crisply and without fuss. It does one thing well, and gets out of your way. It’s not an easy balance to strike.
  • Works exactly as advertised

    By wolftrouble
    Incredibly versatile and stable.
  • Terrible

    By gregnbrown
    This app makes me so upset. It does not do what I expected from it. Completely and utterly ridiculous that there is no obvious way to keep track of your score and find other players!!!!
