Get to know the team behind
Business Calendar 2.


Business Calendar is built by Appgenix Software, a small team of dedicated developers. The company is located in Berlin, Germany and was founded in 2011.

Releasing the first version of Business Calendar instantly became a great success around the world. In 2012 the company released a new app called Business Tasks, available both as standalone task organizer and add-on to the pro version of Business Calendar.

By the end of 2014 Appgenix published Business Calendar 2, successor to our award-winning calendar app. Since then the team continuously works on providing our users with the best calendar experience on mobile devices.


We're proud to have built a tool that makes professional and private scheduling easier for people all around the world. Get to know us.
