Ti 84 calculator

I come from a coding background and really enjoy coding and building projects. I initially created this as a side project for my friends, but when I realized it could be useful for other students as well, I decided to launch it for everyone. The story behind its creation is quite interesting: some of my friends' TI-84 calculators had broken down right when they needed to prepare for exams, and they didn't have the funds to buy new ones immediately. They started looking for TI-84 calculators online; while they found several websites, they encountered various issues—some were cluttered with ads, others had a poor UI, and some had features that didn't work correctly. Seeing this, I decided to redesign the calculator. Although I used the base code from the original TestNav website, I fixed the flaws and improved the UI to make it a better experience for students. I also added new features like timers and games to make it even more useful. So, please visit our site, use it, and support us.
