Trackabi is relatively well developed and thought over product, a worthy contender of Harvest and Toggl. On top of logging time, it can also be used to log leaves.

I rate 4 tacos because there is still room to grow. The interface is not as established as Toggl. It took some time to get used to. Sync between web app and desktop app sometimes not instantaneous.

However, it's reasonably priced time tracker with similar features to Toggl and Harvest.

Even though I don't give 5 tacos, I'm rooting for this product and the company to succeed!
