Trackers

I am getting into trackers, as in Quantified Self.

But the tracking apps that you have to invoke manually are too high overhead.

I used to use a chess clock to track time working versus lost to IT bugs.

Idea: extend and adapt this for multiple trackers.

E.g. start off with an Android chess clock like tracker.  Big buttons saying working, lunch, hung, ...

Extend to scroll through a list of tracker/samplers.
