*** We’re working hard to update Digits for iOS 11 with awesome new features, UI refinements, and 64-bit support! To celebrate, you can now download Digits at a discount for a limited time! ***

Get organized! Conquer numbers on the go.

We're human. We're busy. We make mistakes. So we designed a calculator for humans, from the ground up. Digits combines the edit-ability of a spreadsheet with the simplicity of calculator. Dare we say it? 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 great for:
• Adding up expenses, labeling and emailing them
• Doing a quick calculation and being able to double-check and correct entries with ease
• Entering a long series of calculations and then emailing it to yourself for import into Numbers or Excel
• Quickly calculating a couple scenarios by editing any previous entry to automatically update the total
• Easily creating a grand total from a number of previous calculations with flagging
• Keeping a series of short calculations available for later reference
• Sharing via email, printed output or by files.

• EASY: perfect for a quick calculation, powerful enough for pages of them.
• MADE FOR iPad: uses the whole iPad display to leave cramped buttons behind.
• MADE FOR iPhone: all of the iPad features on an interface designed just for iPhone.
• TAPE: never lose track of what you've entered.
• PRINT: print-quality output with AirPrint (where available).
• SHARE: Use iTunes File Sharing to backup and share .digits tape files to other Digits Calculator users and your other iOS devices.
• EMAIL: tap to email your tape.
• COMMENTING: label any item in your tape and include comments in tape emails.
• CORRECTIONS: make edits and inserts to previous calculations at any time!
• SIMPLE TAPE STRUCTURE: one calculation on each tape line means quick one-touch access for edits.
• AUTOSAVE: holds your calculations and tape in place for the next time you return.
• RUNNING TOTAL: always displays the total above so you can focus on what you're entering.
• CUSTOMIZABLE: a wide arrange of settings, including currency mode, sound and background color! ;-)

Absolute FAVORITE Tape Calc


I LOVE this app SO MUCH!!! I love the simplicity of it, and it's Great for when I have to use large sets of data, like many areas or sums of money. I really enjoy that I can customize the color of the keypad and add notes to specific numbers. I find it very practical and handy that you can save multiple documents (which I, somehow, only recently discovered). This has been my absolute FAVORITE tape calculator app for many years, and I honestly was SO devastated to find out it would not work with iOS 11, so I deleted it so I could get used to life without it, only to reinstall it within a couple days because I wanted to use it for something, lol. I honestly was considering not getting iOS 11 so I could keep this app (which is silly, but I love it so much!) I instead decided to contact the developers, so I went to the App Store, only to find out that they're already working on making it compatible!!! Honestly, this was probably one of the best parts of my day: finding out I'll get to keep the "Digits" app. :)

Great Calculator App with Unique Hook


There are lots of calculator apps on the App Store. I've tried a bunch of them. There isn't much to separate most of them apart from visual styling of their buttons and layout; whether they offer a scientific mode or not; or if they have a memory tape feature.

Digits doesn't have a scientific mode, but it does offer a memory tape with a killer bonus feature that makes it stand out in the crowd — you can save, edit and annotate the tape record, and changes to the running calculations contained therein are updated immediately. This makes Digits super-easy for making up documents such as a simple financial assets statement or household budget, which you can save, archive, and copy from to update with current values on a regular basis.

(If you are looking for a good calculator with scientific features, "CalcBot" is nice, and includes the oft-requested conversion tables as well. Carpenters and students might want to check out "Fraction Calculator Plus" as it makes entry of calculations involving fractions super easy.)

the best calculator. period


+five stars to the devs for commitment to their app. no silly changes or massive "upgrades" that change the whole UI ... nope, these guys keep getting better and better while keeping the original beauty of the app. perfect.

*every time the app is launched there is a warning from the app store... "this app needs to be updated and may not work with future versions of ios". so after five years of using this app and all its clever well-designed features, naturally panic set in. immediately looking for a replacement (to no avail) and hoping the developer hasn't abandoned like so many others do, I waited. then lo and behold the message I'd hoped for arrived, a compatible version is being developed as we speak. my advice to everyone who uses numbers and loves clean, minimal, functional design: download now. I will happily pay for the new version if required. honestly can't remember if this was two dollars or five, regardless it was worth it times ten.
