  • Best calculator

    I love this calculator. Easy storage of each calculation makes checking your work a breeze. I wish I could find it for my iPhone.
  • Best iPad Calculator App

    By SB4VR
    Tried many. This one is by far the best. Virtual tape to review calculations. Great scientific and regular keyboards. Intuitive interface. Highly recommend!
  • Price gouging App?

    By Wehms2
    I would like this App a lot better if I hadn't had to pay for it every 4th or 6th or 9th time it upgrades!!! I guess this last time it did at least add a couple of functions it did not have before.....
  • Won’t clear to start new calculations.

    By digtallydestryed
    How do you completely clear so that you can do another calculation. Very frustrating to not find instructions.
  • Keys are too touchy and slide. When pressed there is a delay

  • Advertisements in paid version

    By scavetta
    I paid for the pro version, yet I receive advertisements from the developer about other apps, which they make and sell, that they think I might be interested. What I am interested in is using the app without annoying marketing distractions. Disappointed.
