About Century Light

At Century Light, we’ve dedicated ourselves to building high quality, usable apps. Calculate84 was built with these ideals taken to heart. There was a lot of push back for creating a graphing calculator in an already saturated market; However, from our experience in school, we knew we could do better.  

The first six months were spent building an MVP and conducting in-person beta tests with three local high schools to ensure any usability issues were fixed. And now, four years later with the help of millions of new users, we continue to read every piece of feedback to constantly improve the app.

Our apps are built by developers and users hand-in-hand to make the best quality products possible.
