Business Calendar started out as a side project, a one-man show,and is now run

by a team of eight in Berlin. The app was very successfulright from the time Android entered

the mainstream market, andit now has an active user base of 2 million. But instead

of modernizingthe design and usability regularly, the developers focusedon implementing

user requests and customization options.
