Teachers - want to level the playing field in your classroom,
reduce distractions, and uphold testing integrity?

Now you can with GraphLock, an affordable scientific and graphing calculator app with a lockdown mode.

Lockdown Mode & Classroom Monitoring Platform

As a teacher, you can use GraphLock from your computer, tablet, or phone and it is always free for you! The teacher version allows you to use the calculator, create classes, and monitor lockdown sessions.

Our Lockdown mode keeps students from using other features on their device- meaning no calls, no texts, no other apps! During Lockdown, a student can only access the calculator and an emergency call button. Then, if they do try to get out, you will automatically be alerted in your classroom monitoring platform.

Calculator Features

Our calculator is simple to use and powerful. Your students can use GraphLock in Lockdown and Non-Lockdown Mode, meaning their device functions as normal. Our mission is to provide students with an advanced calculator they can use anytime, anywhere.

The calculator features include but are not limited to: basic operations, trigonometry functions, absolute value, exponents, log, probability, statistics, matrices, and a TVM calculator.

Customize the Calculator

When creating a lockdown session, you can customize the calculator for your class with the exact functionality your students need. Nothing more, nothing less. Simply uncheck the calculator features you do not want your students to have access to during that time.

This also levels the playing field in your classroom because you know every student has access to the same exact tool.

Chat Features

Now, you can send messages to your entire class or individual students, all while keeping everyone’s phone numbers private. You can also send data sets, equations, pictures, and PDFs.

This means, no more having to write the data set on the board and then waiting for your students to enter it. Now, you can send it straight to your students and they can paste it into their calculator to use right away!
