When we designed Convertopedia, our vision was to deliver the first-ever unit converter with no ads, no recurring subscription fees, no spying on our users, and all free to some extent. We were looking to make a product that works offline when you're traveling or in the subway or in an infrastructure made of concrete, and a tool that fits in with the latest trends in terms of design. All of this didn't exist in a single app before Convertopedia hit the App Store. Best of all, Convertopedia is on its way to becoming the unit converter with the most units on the App Store.
