  • Won’t display basic calculator

    By censorthis
    Can’t get the stupid thing to just display a plain calculator instead of the “scientific” display. Beyond annoying
  • Please make a version for iPhone!

    By Trysta1217
    Great app. Clean. Well worth the money to remove adds. But why is there no iPhone version? The iphone calculator is too basic. I would love to have the Calculator Pro app on all my devices. I can't find anything as good as this app in the app store for iPhone.
  • No ads…great app

    By Roger Ster1ing
    For $2.99 in 2022 I found the no ad calculator to be a great addition to my iPad!!
  • Meh, Keep Looking

    By sutusa
    I just spent a few dollars so you don’t have to. This calculator looks plain and straight forward, which is why I initially liked it… but the UI is off in some places and bleeds into the top bar of my year-old iPad. Had trouble closing the sliding history window too and had to force close the app each time I tested. Doesn’t seem well coded or tested to me. It also just asked to know my location when launching it today… I decided that there is no real reason a calc needs to know that, It felt scummy. I just uninstalled it and will keep looking. Hope this helps someone.
  • Made to buy AGAIN

    By Fphilosopher
    Bought this right after I got my new IPad air. Installed it, loved it… then recently it went all white! There was NO app showing at all when I opened it, just a white screen. So I figured there must have been a glitch and thought I would delete it and reinstall but it wouldn’t recognize that I purchased it even though it said on my screen. I had to find a new version for 2.99 and install just to return to what I had been using all along?! That’s not right.
  • Best IPad Pro

    By Vital Capacity
    Just right to take it everywhere, and do you work
  • Don

    By Elizabeth rivers
    I want for everyday math
  • Don’t ask for reviews.

    By make twitter decent again.
    When I am using the app don’t ever ask me to rate it. I will always give it the lowest rating possible.
  • Why do decimals look like commas?

    By User873926
    Functionality of this app is great. But why do the decimals look like commas? This is SUPER ANNOYING and makes it more difficult to use easily. Please make decimals look like normal dots!
  • Does not do as advertised

    By donp058
    Have IPAD PRO IOS 13.6. After paying for full version, it does not work while working on other apps. Only takes up the entire screen to use in its own app window. Does not work simultaneously while utilizing other apps.
