Quick Graph

I've had this app on my phone for an eternity, and it just continues to work when I need it. No in-app purchases other than a one-time $1.99 purchase (I forgot at first I'd made this purchase, but it's honestly less than most stuff costs these days). No data collection. No one trying to advertise to you in the app. It just works. Not all heroes wear capes, but this app developer is a hero.

If you’re taking any math course, this is a powerful tool to help visualize what you’re working with. I’ve used this since Algebra I and I’ve always wondered what the point of the 3D graph was and how to use it. Now I’m in Multivariable Calculus in college and I use the 3D graphed regularly. This has helped me visualize and understand tangent planes, and 3D functions. I wish it could show points of intersection on a 3D graph (maybe it does but I haven’t figured it out yet) but it does more than a lot of other calculators do in a more elegant way. I love this app, and I recommend it to anyone pursuing math, engineering, or even the high school student looking for a fast, cheap, and simple graphing calculator

Concise, simple, efficient, professional. Does the hard work to minute detail. If one uses math daily and had enough of the false pretense interfaces, this is their Math App. Being able to visualize surfaces at various contrast levels helps with relative orientations and identifying their intersections. The 3D perspective from any angle is accurate. This app was created by highly professional Math aficionados. The community is in debt !
