Some quick hit updates:
Very neat app that is visually attractive and does have some project management merit. However this is not for the enterprise user. This is best usited for a small to medium size company that does not have a project management standard in place. Has Dropbox integration. I may use this for personal or home projects as it is a very organic approach to project management. It is just limited in scaling it to larger, more task centric projects.
Just got this a week ago. If you use MS Project (I know it is a pain) this is a great app. You can view, edit, and even create Project type task lists and Gnatt charts within the app. It allows for Dropbox syncing and, if your work allows, dedicated project server syncing. I'm still playing around with this and hope to have a better review in a few months.
ETA: Moderators, please feel free to change "PM" to "Project Management" in the thread title to add clarity. Thank you
