We believe students and teachers should have a choice other than the same expensive, difficult to learn and use dedicated-purpose TI calculator they have been forced to use for decades.ClassCalc provides a multi-subject math calculator with scientific, graphing, and matrix functionality in an easy-to-use smartphone app. Teachers are able to lock down the student’s phone to only the ClassCalc app for class time, quizzes, tests… no cheating or outside distractions (social media, texting etc).
