The design looks sharp enough. Unfortunately, this space is pretty crowded with great free apps.
I am very aware that this market is very crowded. I don't know if others will agree with me, but I believe the market is crowded with informal generic task management apps. The majority require a sign-up, and don't update in real-time, you need to refresh the page to see other peoples' changes.
I'm hoping to find a slice of the market who would find this app more suitable for their needs. I'm quite open in the direction I'm going to take it, but I'm hoping that the 1-click start, the collaborative nature, and the simple concept will give me a decent foundation to squeeze my way in.
