"RetroCalc" aims to be your go-to numbers app with its refined visuals and nostalgic design.

Sadly the iPad does not come equipped with a calculator. Don't freak out, I've found the top six calculator apps for iPad. Watch to see why PCalc Lite, Soulver, Calculator for iPad, Digits, Calcbot, and Jumbo Calculator are on the list.

Calc XT will be available for free for the next two days, allowing you to finally obtain that go-to calculator app for your iPad.
