Do you have any plans on adding a "manual entry" form or something? I'd love to use this to track how many cigarettes I smoke per day for instance (currently I'm using a small app I made myself).
For trackers for Facebook (twitter, github ...), I planned to add a system of addons to add in one click a tracker for the service (which use the Facebook API), but I'm not sure yet what is the best implementation for this. For the moment, you can use the API (or a library : python or javascript) to track events with scripts.
No manual entry yet, but it'll be added soon. But you can write a python script (10 lines of code) to do it for you : https://gist.github.com/SamyPesse/6859673
(Sorry for my english, I'm french).

Really this is what I have been thinking about building myself, awesome that you actually built it! I think I found a github project that I actually would love and can contribute to!
Cool, I'll definitely keep an eye on this project!
