We’d genuinely like to hear from you, whether you found an error somewhere on the site, ran into a bug with the calculator, have a question about a specific TI-84 function, or want to suggest a new tutorial or comparison guide we haven’t covered yet.

This site is actively maintained, and reports from real users are one of the main ways we catch mistakes and figure out what to build next, so please don’t hesitate to reach out even for something small.
