User reviews

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.

It is not free as advertised

They will charge you down loaded. Avoid this if you can . I did not see my review

Just like a TI84!

So helpful for stats! Definitely worth the $30!

Table issue

App is great but when I try and pull up the table for an equation in y= the app just closes for some reason.
