WolframAlpha is a computational knowledge engine on the web, and with their iPad application, you can perform calculations and look up information even easier. WolframAlpha is a universal application, so you pay once but receive the optimum experience on both your iPhone and iPad.
For mathematical expressions, the keyboard has an additional 3 rows of numbers and symbols. Tapping “more” on the keyboard will expand the keyboarding adding 4 more rows of symbols.
When solving advanced problems like integrals and derivatives, WolframAlpha not only provides the answers, but displays the steps taken to find it. The steps are very clearly written with sentences describing the procedure.
The mathematical abilities of WolframAlpha are excellent, but it’s not all the app has to offer. You can look up information on anything scientific, stocks, weather, health, linguistics, people, organizations, sports, music, and much more. -iPhone Blog $1.99
