Mac: harvest menu bar time tracking

I need software similar to [login to view URL] but for harvest. They actually have a widget for mac but I want a "real" interface like DynMite. I will create a private repository on github where you can work. You should be able to write clean and light code with small disk access and CPU usage. Having some experience with working with web service API would be great. If you think that you need to develop a objective C library for using the harvest API, It would be preferable to write a completely independent code so we can release this part as an open source project. The interface should be translatable although done in English first. [login to view URL] [login to view URL]
