Provide a simple screen showing hourly activity. The 24 lights at the bottom of the clock show the activity for every hour of the current calendar day (green when above 500 steps, yellow when above 200 steps).

Steps and stairs are green when goal is reached, and yellow on 60%. Battery is yellow under 40% charge and red under 20%. Second step counter is the number of steps for the current hour.

Due to the way this hourly data is calculated, they will be reset all to red when an exercise is done.
