  • Provides misleading information

    By MickyApp
    Programmer assured me that by paying a one time fee that the pro version of this app would not contain advertisements. Was incorrect and mis leading. You will continue to be interrupted by advertising ... you are better off using a free calculator app.
  • Good calculator

    By Terryb68
    I like the calculator and what it does but I purchased the app so I could get rid of the ads! No ads for about 5 days an snow they are everywhere why did I pay to get rid of ads and I’m still getting them! That’s my only complaint!
  • Best calculator app, but flawed

    By scotty321
    This is, by far, the #1 best calculator app in the App Store! It took us 9 years to find an app like this! This calculator app is incredible. It lets us copy and paste numbers from other apps, it works with iPad features such as SlideOver and split screen, it has built-in currency conversion, it can be used as a widget, it is blazingly fast to launch, it is easy to use, it is accurate, and it comes with some amazing skins! We love the high school sketchbook skin!! The only bug/problem with this app involves currency conversion. After we complete a currency conversion and we try to perform a math function on our newly-converted currency total, this calculator mistakenly REVERTS BACK TO THE OLD (PRE-CONVERTED) CURRENCY NUMBER for our math equation, which is very confusing and throws off all of our math functions. If someone isn’t paying very careful attention, they won’t even realize that they received the wrong total on this calculator. We have experienced many, many, many math mistakes because of this bug/problem with this app, and we only caught it a few times because we weren’t paying close enough attention. Once this bug/problem gets fixed, this app will deserve 5 stars.
  • Useless

    By 臭臭要爆炸
    Ads? I understand. But now it just freeze at the starting screen with introductions to new features and cannot be closed. I can only tap on ads or paying to fully upgrade it. Come on people, it’s shameless to launch an app that cannot work and ask for money. Shameless!

  • Bought Pro but still have ads

    By QuatoQuato
    Bought the Pro version where it said no ads, yet here we are
  • Good

    By Bruce McLeod
    I like this Calculator and I upgraded to the Pro version, but recently had to wipe my iPad and reinstall everything. Can’t find how to restore purchases like other apps. I’m only out another buck, but you expect things to work right.
  • Way too many ads

    By FairCritique
    Way too many adds that it keeps interrupting. So annoying that I had to delete the app. =update= To Apalon Apps, to reply to your response... I understand that you work hard to create something and you should get paid for it if a consumer believes your product deserves to be purchased. But also there are other calculator apps that are free and work just as well as your app does with a lot less ads. As a consumer, I naturally got one of those apps after deleting yours. I’m ok with getting ads because I’m trading it for not paying money. But as for your app, the amount of ads that I got (more like was bombarded) was unbelievable, so that made me want to write a review. That is all.
  • clean interface & great widget function

    By Mtsu1272
    Love this simple app. Since calculator is not a built-in app on ipad as on iphone, i have to look for one that just works without too much distractions. This app serves the purpose seamlessly. The clean interface and widget function are welcoming bonus.
  • The worst app ever

    By Globetrecker
    I understand that it didn’t cost me an arm and a leg to purchase a pro version but I thought I was paying for ad free experience. What a bunch of crooks these developers are! In short, you are paying to see ads. You won’t see the calculator because ads keep popping up. Apple should remove this app altogether and not endorse this kind of unscrupulous creeps who cheat.
