"Asana is the work management platform teams use to stay focused on the goals, projects, and daily tasks that grow business"
It's an amazing piece of software that I use everyday. Use this with the ideas in the book "Making Ideas Happen" so you're not the type of person that says "I have an amazing idea" and be the person that says "I did this amazing thing" instead. It's free and has a great iOS app. I assume the Android app is equally good. Plus it's free for small teams and it's perfect for collaborating on projects as well.
