This clever calculator app solves math problems with numbers and words. For example if you entered “20% off $50k” Soulver will give you the answer “40,000.” Using words with numbers lets you give context to your calculations, mimicking how we think about math in the real world without overwhelming us with spreadsheet programs and calculators. The app can also perform currency conversions and other units as well as stock calculations. Watch the demo video below to see how it works.
Soulver is available for the Mac, iPad and iPhone. If you don’t want to pay for the app you could also try a free competitor called Numi.
