Looked around for a simple calculator with a few advanced functions. The ones I found were either very basic four functions or very advanced scientific calculators with tiny keyboards. This calculator is amazing, it hides most of the keys you don't need so you don't have a cluttered keyboard for the basic calculators you do most of the time, yet it has the ability to do the most complex calculations.

Great app for my 5s, not working w the 6 plus

Hello guys, I am giving 5 stars because this is a great app that always worked for me on my iPhone 5s. I just got the iPhone 6 plus and now there is a zoom on the calculator so I can not use it because I can't see all the numbers. Please look into this, I would like to continue using it . Thanks !!


This is the best calculator for the iPad and iPhone ever! Its compact and useful features make me less hassled to go online to check my solving or graphs. Must get the 4.99 upgrade! At first, the scientific calculator isn't that seemingly a strong lure, but they 4.99 upgrade makes thing thing shine and it's awesome! Strongly recommended for middle school, high school, college, or even real world scientists!!
