Why do you want to track everything? Just for curiosity… I had a jawbone and tracked every meal, but after a while I gave up because the data wasn't valuable for me

I interested in building personal, private analytics dashboards to find previously unknown personal correlations between inner moods, feelings, emotions and health states with external factors, such as food/drink intakes, duration of sleep, exercises, travel patterns and other trackable activities.

I also want to visualize long term events such as quality of relationships (gained or lost), occupations and income dependencies from short and long term habits.

This whole project depends on ability to gain access to raw data feeds and then playing with them.

Does it allow me to access raw feeds data?

Looks interesting. They should get rid of this though: "...Due to high demand, we currently have a waitlist...".

Wtf? are they selling hardware? or their computers cannot keep up with high demand?

I call marketing BS.

Yes, keeping up with demand can exceed the capacity of your computers. It can also exceed the capacity of your code when you discover bottlenecks that didn't appear before usage grew to a certain level. Users demand human resources as well; Anand and Eric can only handle so much customer support on their own (right now it looks to be a 4500 users : 1 employee ratio), and you can't scale staff instantly by pressing a button.

PS: Kudos for them to list data-gathering apps which is useful.
