Note: I don't have a working Pebble anymore. This repository is archived and will not be updated.
This Pebble Watchapp keeps track of any event in your life that you care to manually mark, and displays them in the form of a log.
The point of this app is mostly an easier access than the phone or a piece of paper, and automatically tracking the current time.
I use it to track my caffeine consumption and a few other things that might be relevant, in order to correlate them with sleep data.
