CalculateRetro ($1.99)

Any calculator app can give you basic or scientific calculations. At this point, that’s old hat. CalculateRetro does offer a feature I’ve been looking for ages, however, by providing users the scratch paper that went into their arithmetic. CalculateRetro tracks the keystrokes you enter so that when you’re wondering why the answer looks different than you thought it might, you can find out exactly why.

As a bonus, you can add text to the scratch paper to explain what certain figures refer to, and then email or print out your work right from the app. As someone who works on the go often, there’s something to be said about using a calculator app without having to make absolutely sure you’ve entered in every single number correctly.

Instant Customer ($2.99)

If you’re running fundraising campaigns or managing donations for any size company, Instant Customer is a handy way to make sure your eggs are falling in the correct baskets. The app lets you take pictures of business cards you receive, where the information on the card is then transcribed and inserted into the app.

From there, you can create “campaigns” and put the business cards within the appropriate listing, so you’ll know who to go to when you’re working on specific projects. Instant Customer also boasts that it will perform the follow-up with the contact automatically. Not a bad way to get a leg up in the business game.

SamCard Pro ($5.99)

If you’re looking to simply keep tabs of your business cards without adding them into specific individualized listings, SamCard Pro makes for a good place to start. SamCard Pro lets you take a picture of your business cards where the information is quickly translated into digital text.

Once the card has been entered into the app, you can edit the listing if any errors are present. Soon you’ll have an easy to read listing of all of your business contacts without the need to haul a Rolodex around.
