Best Calculator App - Want’s to track me?

This is by far my favorite calculator app! It does everything! But… Why is my calculator asking to track me across other apps and websites? That’s it, I’m destroying everything I own with a network connection.

One of the best calculator apps

I’m a huge fan of this program. I typically use physical calculators, but this one always serves me in a pinch, and it has excellent references like formulas. I cannot recommend this app enough for any practical mathematicians.
