Good job! I like the interfaces. Haven't found option for piece-rate projects though. Do you have any plans on the matter ? Another guess: I think some API features would be extremely useful for such a service.
Thanks for the feedback, I agree it would be useful to have the option to set a fixed price for a project. We actually did some wireframes for this a while back, but we never got around to implementing it. Maybe now would be a good time to look at it again.
What API features are you thinking about? We have a pretty limited API that we built for the iPhone app, but it's growing as we work on the next version of the app. So over time it'll get more of the same features as the website.
Thank you for the answer!
I see two directions for API: one is an integration with existing services api such as RescueTime, and the other is own api to give such opportunity to fellow developers. For example any task manager service can use time-tracking and project/profit management functions at your service via API.
