Calculator Plus is a standard and scientific calculator that has simplicity at its core, while not compromising on functionality. Even with its simple user interface inspired by the built-in Calculator app on iOS, it offers much, much more - and with no ads!

With full expression and live answer preview, be faster than ever at calculating, see exactly what you typed. Understand your answers by displaying them in exact form, scientific notation, fractions and more. Catch the exact errors with helpful syntax errors, with beautiful animations to complement your calculations. The full scientific calculator is also present in the portrait layout, so now you can calculate scientific operations away one-handed on your phones.

That's not all! If you're on a Mac, or have a hardware keyboard connected to your iPad or iPhone, simply type your math expressions normally and it will be registered - including every scientific operation listed. On an iPad, your Apple Pencil works with iPadOS 14's Scribble to allow for direct handwritten inputs - no dedicated handwriting panel, just write anywhere on the calculator!

Bonus features: With voice dictation input optimised to understand mathematical expressions, calculate any expression quickly and efficiently. Clipboard support not only allows you to copy your calculations for others to see, it also gives you the ability to instantly take any expression from anywhere and paste into the app.

What’s New

Version 2.1.2

- Fixed keyboard shortcuts on the numpad - the Enter and Clear/NumLock keys now correctly trigger "=" and "AC" respectively.
- When an answer is computed, "Copy Full Calculation" now has a separate keyboard shortcut, while the usual CMD+C copy keyboard shortcut now invokes "Copy Answer".
- Updated watchOS app calculator interface layout and complications compatibility.

Note: Version 2.1.x are the last versions of the app to officially support iOS 9. Version 2.2 and later may require a newer iOS or iPadOS version to function. For macOS and watchOS, the OS requirements are not affected.

Small Download, no Ads

I just wanted a calculator that honestly should have already been sent with an iPad (considering all the bloatware I received but never asked for). This calculator works, it has no adds, and is very small in size. I think 8mb, but don’t quote me.

Thank you for taking the time to build this for people, you saved me some time and money. I figured it was the least I could do to rate it. Keep up the good work.

Great calculator app, a must have!

After switching from another calculator app, Kalkyl, I wanted a calculator app that was still being updated, was free, and had no ads. So far, this fits perfectly! My only suggestion is a unit conversion function, as I tend to do a lot of that sort of thing, but it’s not a turn off, so it’s fine. Great work from the developer, very pleased.

Great app for iPad or iPhone. FREE. ZERO DATA COLLECTED. There a so many calculator apps to buy, and all of them track you in ridiculous ways. Why would anyone pay money for that? This app is fantastic! Try it out, you won’t regret it. It took me forever to find. I think this app should be on Apple’s recommendations for free apps. I’ve been using it for the past year and had zero issues with it.
