Review, and I paid for this

I’m leaving this review because of a glitch and so you see it; your calculator does not allow people to input negative matrices. Like, you can’t input “-2” or anything as a value. Thank you. Please fix this and any other glitches ASAP.

Thanks for your feedback.To enter negative values to a matrix, make sure to use the negation key "(-)". The normal "-" key won't work here.

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.

Ok, but it could have more features

I think that this calculator could have more features, such as creating programs, and all the other features the TI-84 Plus CE has which this app doesn’t. I wanted a reliable replacement to the actual calculator on my phone, and this is one of the closest I could find, unfortunately it does not have all the features of the real TI calculator. Also, I think a one-time purchase would be better than a yearly subscription to the app.

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!
