Vibrates twice at every full hour.
New setting: sun dial. The dial is split by a line from sunrise to sunset (for the date and your location): bright day, dark night, with own colors for day, night and the line. Text stays readable on the line. Needs the location permission of the Pebble app.
New setting: show the running hour in a bigger typeface on the dial, with its own color (off by default).
First release.
