Get this, not Downy

If you search on the App Store "Downy premium calculator" it shows you the BIGGEST ripoff and plagiarism. Downy totally just stole this from Desmos and tried to make money off of it. They should be sued because Im pretty sure Desmos is copyrighted. Desmos is in fact the original owner of this amazing free graphing calculator and no one should bother getting Downy.

I use this calculator all the time to quickly see what a function might look like and to see if my solutions to problems are correct.
Last time I used this was today when I wanted to see if sqrt(5) really was the vertical translation of a circle (with radius=1) be inscribed inside abs(2x). Then, thanks again to the power of Desmos, I could very easily alter the equations with a slider to prove that the height of the circle will always be sqrt(n^2+1) to be inscribed inside y=abs(nx).

This calculator is perfect for people who want to perform complicated mathematical experiments and for the people who just want quick answers to common calculations. Its for anyone.
