PCalc App Reviews

  • Best alternate for the now defunct M48+

    By Esorcc
    Would be perfect if it had units associated with data. I was a long user of HP48s and the the M48+ app. Sadly when I upgraded my iPad recently I found that M48+ is no longer available. PCalc seems to be the closest match. Programming is not near as nice as HP48 style. Also PCalc cannot work with units tagged data. It does have units conversions but the unit is not associated with the data. The best feature of PCalc is the customized key layouts. You can setup layouts for different types of work that needs to be done.
  • Get it

    I can’t give this app enough stars. Brilliant!
  • Looking forward for edit numbers on screen

    By Obadiahcruz
    Great calculator! Cannot wait for an update that allows me to edit the numbers on a tape or from the screen. Saves major time and I doesn't have to keep swiping left and retyping everything again. Thank you
  • Still no graphing, alas

    By jeffwatkins
    This is the best calculator you could ever want, especially if the calculator you want has a full 3D video game built in. Take a break from those numbers and relax.
  • Awesome Calculator, Awesome Developer

    By __JN__
    Best Calc app that I have used. Have lots of Calc apps but this is the one I keep coming back to for all needs. Engineering, Math, and even casual grocery store stuff. The nicest thing is this developer actually understands and supports all of the iOS versions that are claimed to be supported. Can't say that for other developers, some even "big name" developers. Thank you guys for a great product!!!
  • Will not install on Apple Watch 4 v5.1

    By Loosegoose2
    I had PCalc on my iPhone and Watch 4 and it worked. I upgraded to v5.1 on the watch and then that was pulled a few hours later. I did this current update and it works on the iPhone but will not install on my watch.
  • Best calculator!

    By Geohough
    Great program! I especially like the Apple Watch app! They keep adding features! I wore a Casio scientific calculator on my wrist for 30 years, but I have finally have a modern replacement. Thank you!!!
  • Great calculator; watch complication needs work

    By orennyc11
    Obviously this is the best calculator on the phone. But the watch complication work is not there. Friendly suggestions: 1) offer a variety of options for what the various complications look like. 2) offer an infograph modular complication that displays info from the calculator, at least showing numbers or constants or something... 3) the top of the infograph complication should serve a similar purpose with text. Use the watch guys!!
  • Apple Watch 4 full support?

    By Product manager
    I looked forward to the update — is it possible to use 4 columns of calculator buttons on Apple Watch 4? The main operators would make this app and watch awesome! You’d still go to the second screen for the four that don’t fit.
  • Needs 64 Bit Support

    By Jim92677
    PCalc is a good app but if it is going to provide number base operations (hex, octal, decimal, binary) then it needs to add 64 bit support. Even cell phones are 64 bit. Software developers work in 64 bit environments while PCalc only provides support for 48 bits. I have emailed the developer at least 4 times since 2011 and still no 64 bit support. Lack of 64 bit support is inexcusable in this day and age. The best calculator for iOS bar none is free and the name of the app is Sci:Pro. It is 64 bit and has everything that you need at no cost. I give PCalc 3 start because it does everything else very well, but if you want to save some money and deal with a very responsive app developer, give Sci:Pro a try.
