Asana App

For project planning, I love the Asana App. If you're working with a team that each handles different things (marketing, logistics, design, etc.), this is an especially useful tool. I even use it for solo projects; for example, as a real estate agent I created a single task list for buyers/sellers, and I can regenerate that list and check it off as I go through the process of each sale. It keeps me organized and on schedule.
