Get organized! Conquer numbers on the go. Digits 3 is a top-to-bottom rewrite made for the latest iOS and devices.

We're human. We're busy. We make mistakes. So we designed a calculator for humans, from the ground up. Digits combines the editability of a spreadsheet with the simplicity of a calculator. Digits is a calculator a human can love.

So, why do so many humans love Digits? Its uniquely correctable tape means never worrying if you entered a calculation correctly. Make a mistake? Tap any entry on the tape to correct it (or edit, insert, copy and more). Then, add a label/comment and email or print the tape.

Digits is Shift’s highly-rated iOS calculator app that features an intuitive, fully correctable and editable line-by-line tape history. It uniquely provides spreadsheet-like editing with calculator-level simplicity. Tapes are stored as documents so groups of calculations can be stored and edited conveniently. Comments can be added to each calculation line, making the app ideal for expense tracking and budgeting.

Digits 3 highlights:
• An updated, polished user interface with buttery-smooth interaction.
• Dark Mode and detailed color and sound customization.
• Multi-threaded processing for desktop-level performance.
• In-app upgrades, starting with Tape Document sharing (via Messages, Mail, Dropbox and other popular file sharing services).
• Built from the ground up with support for 64-bit and the latest iOS/hardware.
• Designed to maximize resolution on devices like the iPhone X.
• Split View support on iPad for side-by-side work.
• Expanded in-app help.
• Accessibility VoiceOver support.

How Digits earned its stars:
• Spreadsheet-like editing with calculator-level simplicity.
• Fully correctable and editable line-by-line tape history.
• Fluidly enter values, label and email or print.
• Double-check and correct entries with ease.
• Export Tape Documents in a variety of formats.

Button functions:
Delete row, backspace, clear all, clear, memory, memory plus, memory minus, plus or minus, tape browser, percent, export, settings, shop, tips, help, edit, insert, total, copy, use, comment, flag, sin, cos, tan, square, cube, exponent, square root, cube root, root, inverse, Euler, Pi, add, subtract, multiply, divide, total.

What’s New

Version 3.1.2

The calculator that edits, comments, shares, saves and prints, has gone Dark. Dark Mode is now supported as standard in iOS 13. And we’ve added Smart Color Sets to keep your keypad looking great as you toggle between Light and Dark.

I waited the entire time for the update!

This is the calculator app to have. Incredibly easy to use and I would gladly pay more for the app than they are charging. I was in an accident awhile back that left me with brain damage. One of the complications is short term memory loss. This app was invaluable to me and when I couldn’t use it because it wasn’t compatible with the new iOS update, I went into small panic mode. I downloaded at least 20 calculator apps and only one of them was remotely useful. I never deleted this app and would periodically check to see if I could open it. You can’t even imagine how happy I was when it actually opened. If you’re questioning if this app is worth downloading, it is.

Awesome App - Rare Features & “Human touch”

Dump every calculator you have, I had 4 before I found this, they all sucked because they did not touch on the human being side of things like this App does so well.
Very few app creators are remembering that there is flesh and bone on the other end of these devices, this app nails it.

#1 BEST FEATURE (for me): has to be the “comments integration”, it’s the only reason I bought it at first actually, I’m hoping they will expand even more on the identification elements of each mathematical entry, it’s so nice to see exactly what each line represents “in real life”, so to speak....which is challenging considering the limited amount of real estate on these phones, I get it. Nice.

#1 RARE APP FEATURE: (I’ve never seen this on a “Utility” App).....the Customizable Color Wheel in settings...It actually has a semi-full color range HUE slider, with saturation etc....that’s really rare (Outside of the Smart-Home lighting Apps themselves)...these guys are on point.

(Why a 4?) = Overall 1 dope App, but yes I am a stickler, I am missing the ability to enable ‘Night Mode’, which is mentioned in App description & screenshots....But I do see it: it’s under the “Upgrades Tab”, for purchase @ .99 (I assume), but it still says “coming soon”...?
(I’ll bump to a 5 soon as its working tho!)

DEVELOPER(s) —> keep up the good work - mention the Color Wheel in your description & boost those downloads even more....

Thanks so much for taking the time to write up a detailed review. We’ve read it over and will definitely consider your suggestions. One thing to note: The latest update does have support for Night Mode (and more!) with the Pro Design in-app purchase. We'd appreciate an updated review once you’ve had a look!

Fantastic calculator, but please add smaller keypad

This was just what I needed after buying my first iPad Pro and discovering there was no native calculator app. That’s ridiculous by the way, but good for this app I suppose. My suggestion is that you create a setting for the keypad to shrink down to normal calculator size when in portrait mode. It’s absurdly large in that orientation, even for my big hands. The smaller keypad setting in landscape mode is just about perfect. Thank you.
