Meet Tandem. Tandem is an app designed specifically for cyclists in order to allow fellow enthusiasts share in their passions. Discover popular trails in your area and customize personal cycling routes as well! With the ability to plan routes you can even go as far as organizing special group events with ease. In addition, you can locate friends on paths, and share trails and post your cycling accomplishments on your profile. The goal of this project was to create a brand, mobile platform and learn how to use Principle.
