The best Calculator app

This is one of those apps that’s so good, Apple should’ve done this. The longstanding ability to use brackets to do longer calculations all at once was what enamoured me to this app for years, but now with the swipe gestures for quick access to useful functions has made this the perfect calculator app. There’s really nothing else you need in an app like this and I’d recommend it to everyone.

Heck, I’d even pay for this app, so I don’t know if there’s a better endorsement than that.

The best calculator app and developer

Easily the cleanest and most practical calculator app on the market. I love the amount of appearance customisation options and that feedback has been listened too. 11/10 would recommend. Thanks :)

Perfect…

Well done. Beautiful design and layout. It’s so much better than before. Thank you for not going subscription.

Love the new updates

The new updates brought a fresh new look and more theme options which I love. It’s good to see that this app is still being developed. I was worried that new iOS versions would leave it behind

Amazing

I fear the day this app will no longer be available or something happens to de devs. This app is the biggest reason why I stick to iPhone rather than switching to android lol. Lately the developers have updated the app frequently and it's awesome to see! Keep it up ya'll! BTW I see why I kept missing the decimal point 🤣 didn't realized that was moved until the latest update where you made me chose where to put it. Thanks for everything
