  • Glitchy and manipulative

    Read the title. And get rid of the freezy and sneaky adds. Thanks that’s all I have to say.
  • Forwarded to my enemies

    I used this app for years. It was highly functional. The current version is way too intrusive, taking over entire screen to push developers agenda. With soooo manny better options, it was deleted.
  • Flawed

    This calculator is deeply flawed. When using percentages in calculations it will return the wrong result. I have tested it against every other calculator I have.

    By Jo Jo355
    I, like many who paid for ad-free, have used and loved this calculator (scientific, especially) for years. However, like others here have mentioned, since the last update the scientific functions are no longer even viewable and the "base" calculator is BEYOND distorted. Perhaps you forgot to test on all but the very latest version of iOS? At any rate, it is utter garbage on iPad Pro (LANDSCAPE) running the last version of iOS 12 prior to 13 (many of us are NOT keen to jump on iOS 13 as we've heard it has many, many issues). I have NO other apps, paid or not, with this type of issue. FIX, AND TEST YOUR UPDATES IN THE FUTURE! Adding new features at the expense of stability is not smart.
  • Dreadful widget and app now

    By pdj2225m
    I am deleting this app now having been unable to do a simple calculation in either the widget or the app for 5 minutes. The widget seems to have a history that you can't see, so my results made no sense, and I could see no way to clear what I could not see. Then the app interrupted my entry to advertise something. When I returned it complained about divining by zero and failed when I tried to start over. All I was trying to do is to convert Fahrenheit to centigrade. I wonder if it also knows that 1+2+3=24? Zero stars!

    Highly disappointed to pay for the ad free version and have multiple ads immediately become in our face! Closing the app and restarting did not help. I have used this app happily for years and am really unhappy with what this version has become.
  • Just keep adding

    By Arghonaut
    Do you want a calculator that never completes a function? What’s 12 x 347? Get your answer? What’s 132% of 48? Did you remember to swipe left on the clear button like a real calculator? If not, this app just adds the next numbers you wish to calculate to the previous ones, which is annoying and terrible. The calculator on a windows computer is more intuitive. Deleted from iPad. Developer response to my review indicates they have never used a calculator before. Do not trust. 2+3 might equal 21😔. It’s all there in my original review: make a calculator that behaves like a real calculator or get off the App Store. Hey hey: this calculator and the App Store: two things that are wastes of time!
  • Do NOT waste your money

    What garbage. I can’t believe I PAID for a calculator Ap (to remove ads), and the screen is always distorted. Deleted and reinstalled, but still distorted. Unusable.
  • Last update made it unusable for me

    By Bjorgens
    I have not been able to use the app since the “fantastic converter feature” was introduced a couple months ago. The “I Understand” button does not work for me, so I can’t get past the introductory screen. (My IPad Pro is less than a year old, and system software is up to date.) hopefully this will be resolved soon - it was a 5-star app for me prior to this glitch.
  • Ads in a paid app?

    By JimboDev
    This is seriously messed up to pay for something and have to endure the interruptions of ads. I will remember the name of this developer and never use anything they produce from now on.
