It is still a phone app, so it’s not a perfect remedy for having a physical graphing calculator in every situation, like tests. Not long after, the UI for handling matrices is by far the best from any calculator I’ve ever used. When I first got this app it was still a work in progress, and I sent in feedback asking for them to add matrix functions. They did a really good job of incorporating the power of smartphone to augment the traditional TI-84 experience. As someone who swears by TI-84, it’s incredibly intuitive and has lots of added features to make it more user friendly.


I’ve dealt with many apps that have claimed to be this, or have tried to be this, but this is the first that actually feels like I’m using a graphing calculator. I’m a 3rd year mechanical engineering undergrad, and holy lord crap this is the greatest thing since Betty White.
