Digits Calculator and Soulver are basic calculators designed for everyday use. I use “basic” categorically as both calculators are nothing more than basic. Both apps offer unique features and capabilities that will make your life much easier and more productive.

With all the free calculators found in the Apple App Store, I thought long and hard about whether it was worth paying money for a basic calculator, but found Digits Calculator and Soulver to be a must once installed. Digit Calculator is $1.99 and Soulver for iPad is $5.99. For most people, I recommend getting Digits Calculator instead of Soulver, although the latter has more robust features. Digit Calculator is best for someone who wants a simple and fast calculator. Soulver is more for the person who does complex planning. Having purchased both apps; I actually use Soulver more often, but IMHO Digits Calculator is the better of the two for most consumers.

Digit Calculator for iPad + iPhone

Shift Apps Digit Calculator combines a large and easy to use calculator with a tape. As you enter your calculations, Digits Calculator keeps track of your entries and calculations on a digital tape, just like a receipt when you go shopping. If you make a mistake, you can easily go back and correct it with the Digit Calculator. Just tap on any entry you have previously made and enter the correct data. All totals are recalculated automatically! Digit Calculator also allows other editing features for your tape. You can insert a new calculation between previous entries, copy, add a tag and comment your entries. Once you’re done with your calculations, your tapes can be printed, saved as a file, and emailed.

Soulver for iPad

Design and usability

Acqualia’s Soulver is one of the few calculator apps that takes advantage of iPad’s unique features and large screen size. Soulver for iPad combines a calculator with a notepad that allows you to solve complex calculations without problems.

Soulver supports both landscape and portrait modes. Regardless of which display orientation you choose, you’ll find the Soulver’s display layout closely resembles that of a French-door refrigerator. The bottom of the screen has the input panel where you can switch between a QWERTY keyboard, special functions, and a calculator. The upper region of the iPad screen is divided into two panels. The larger left panel is used to write your calculations and the right panel shows the answers instantly. Lifter also keeps a running total of all lines at the bottom. This makes it easy to track bathroom remodel expenses or plan your budget for the next vacation.

Soulver is like doing math on paper as your work is visible at all times. With Soulver you can go back and change any line. Soulver is unique in that it allows you to use words along with your numbers, so your calculations actually make sense. The app doesn’t run calculations based on the words you type; The words are just an optional reminder and comment feature to help you remember which numbers go with which calculation. (For example, concert tickets were $25 x 3)

synchronizing

Soulver automatically saves your work and allows you to create files for each set of calculations. This lets you go from planning this month’s budget to planning next year’s vacation with just a few taps on iPad. Because the developer created both Mac and iPhone versions of Soulver, you can sync with other Apple devices.

advanced features

Some of the unique features are that Soulver can convert currencies and manipulate percentages more simply with 14 dedicated functions. Plus, there are 14 percentage functions so you can easily calculate sales tax, tips, get discounts, and more.

Scientific functions and variables

While not a dedicated scientific calculator, Soulver has complex functions that you can use. Soulver includes log, square root, factorial, mod, trigonometric functions (sin, cos, tan, etc.) and more. In addition, the application allows you to solve variables.

programming factions

If you are a programmer or computer engineer, you will love Soulver as it supports both binary and hexadecimal calculations and conversions.
