Best calculator app I ever used

Ive had this way back at college I needed an app for my math class. I tried so many until I found this one. I still use it to this day. Its simple enough for quick day to day use. Still, complete enough to do calculus.

Best thing about it is the its color especially when I use it at night as invert the colors in my iPhone. Makes it easy on the eyes.

Highly recommend it.
