About Us | TI-84 Calculator Online

🎯 Our Mission

The TI-84 Plus CE is one of the most widely used graphing calculators in the world. Many math classes in the United States — from Algebra 1 through AP Calculus and Statistics — expect students to have one. But the physical calculator costs $100–$130. Not every family can afford that.

We built TI-84 Calculator Online so that budget is never a barrier. Whether you're a 6th grader just learning about graphing, a high schooler cramming for finals, a college student finishing a statistics problem set, or a teacher building lesson plans — our calculator is here for you, right in your browser.

No signup. No download. No credit card. Just open the page and start solving.

🌍

A student using a school Chromebook and a student using a personal laptop should get the same tool. If buying a physical TI-84 is not possible today, the math homework still needs to get done tonight — that is the whole reason this project exists.

⭐ What Makes Us Different

A Real Emulator, Not a Copycat

Many "online calculators" just mimic the look of a TI-84. Ours is a true browser-based emulator. It emulates the TI-84 Plus CE: every key, function and menu behaves the way it does on the real device. No shortcuts. No fake buttons.

Designed for Special Needs Students

We deeply care about accessibility. Our color theme switcher lets students choose a faceplate color that works for them. The touch-friendly design means students with motor challenges can use it comfortably on a tablet. We designed the layout so screen readers can navigate the page easily, and zoom controls let visually impaired students scale the calculator to a comfortable size.

Works Offline

We built this as a Progressive Web App (PWA). Students can install it on their home screen and use it completely offline — no Wi-Fi needed. This is especially important for students who don't have reliable internet access at home.

No Ads Where It Matters

We do not show ads on the calculator itself. We keep it clean and distraction-free so you can focus on your math.
