User Reviews

Reviews consistently praise calculation accuracy and an ad-free experience, but complain about pricing/friction with IAPs and missing TI-84 features. Multiple users report stability issues with table functions and input handling, and several criticize unclear lifetime upgrades and ongoing subscription costs. Overall sentiment is mixed: strong math performance but significant pain points around pricing and feature parity.

Pros

Accurate calculations and reliable results (including correct exponent handling)
Ad-free interface with no pop-up ads
Helpful for statistics tasks (as noted by reviewers)

Cons

Pricing model shifts toward a subscription with ongoing costs and unclear lifetime upgrade terms
Missing TI-84 features (e.g., numeric solver and ability to create programs) compared to TI-84 Plus CE
Bugs and instability in table and input handling (table crashes, domain errors, negative matrix input restrictions)

Recent reviews

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!

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.
