Insight Pro for Android
Today, I've tried 11 different self-tracking apps for quantified self and this is by far the best. What it does best: (1) Requires very few clicks/touches to do a survey. Couldn't be much faster/easier! (2) Probably the best graphical overview of data. (3) Option to correlate data. There is some room for improvement and I've emailed the developer with suggestions. However, for such a young app getting it right at the outset, my hopes are high.
As a self-quantifier, I am thrilled to have this tool, especially for 1/2 the price of my morning coffee.
Im not biased or anything, but I would say this is the best app on the market.

The app needs instructions, like step 1, step 2, etc. It isn't possible for many people to understand how to intuitively set it up. Add instructions, and you will have a far greater chance at success.
