I've been working on version 2 of ClaroHQ (https://clarohq.com), which is a time blocking app for freelancers. Instead of playing with Start/Stop timers, you log your work with 1-click time chips, generate a perfect PDF, and draft an email in 30 seconds.

I built it because I was sick of paying for complex invoicing tools that charged monthly fees for features I never used.

Let me know if you want to try it out. I'll be happy to set you up with an account.
