Please look

Please add a dark mode. Gives the app more personalization. Also missing a lot of ti-84 features like numeric solver. And you should definitely make the numeric solver specifically free, ya know. 😉😉


Wish y’all success!

Glitch

Overall, I liked this calculator. It was similar to the ones that I am used to. The color choices were nice and I was able to slide it wherever I wanted it to go on the screen. The most important part of a calculator is accuracy. I was very disappointed when I typed a function into a the y= and pulled up the table that my domain was incorrect. There was a random value instead of an error. I even have a recording if this. I tried contacting the email, got no response, so cancelled my subscription.
