Excellent Calculator

Great for single calculations and “chain” calculations.

This is the best free graphing calculator in the app store

Im surprised theres only a few people using this!! It literally has a 3d grapher and theres so many other features that makes this app extra helpful for a calculator!

Good little pocket calculator

As an engineering student this app always comes in handy whenever I don’t have my trusty Ti-84 on me, and it’s the closest equivalent I have found on the App Store so far. Once you get used to the layout it is a powerful app and I’m glad I have it.

Perfect Calculator

This is exactly the perfect calculator for iPhone. In terms of the calculator, it actually shows your the equation as you type it, shows your old equations, and you can pull down equations or values into your current equation. If you’re a mathematician or an engineer and need a real calculator, this is about as good as it gets.

2 wishes:
- an option to solve system of equations (complex, but that’s still why I reach for my TI-nSpire CAS usually, before this)
- optimize for iPhone X ... this app is still running at the iPhone 5 resolution... it’s worrying me that this app is dying off, and all we need is Apple to do what it does best and cut support for some sort of API that this thing uses or something like that.
