Works, Helps.

It just works and gets better and better. The App is a helpful companion to the Webpage and Mac App, providing full access to information and offering tools for communication everywhere. We tried and abandoned several other tools and also Basecamp 2 did not really catch on. With BC3, the Smoothie Integration of Web and mobile Apps, and the intuitive design, it just works and we use it all the time (in a research team in an academic environment).
