Cool services for freelancers

For some reason the Rails community is really into creating nifty tools for freelance designers. (No doubt because the original Rails app was Basecamp….)

ClockWork – time tracker. Enter a project’s name and the clock starts. Includes a handy pause button.
Tackboard – post comps for clients & get their feedback.
Blinksale – easy, pretty invoices.

And then there’s SideJobTrack, which sort of combines some of those things in one place (but doesn’t seem to be a Rails app).
