Pebble in Action Counts how many active pebble users are there by having the app ping to the servers once a day. Main Screen: "Pebble users" - displays how many users were counted yesterday "Today's count" - displays how many users have pinged for the current day and is expected to rise up until end of day GMT Notice: This app will automatically launch every 12 noon and will close automatically after it has pinged. Information sent includes your pebble's unique ID(to avoid duplicated count) and your GPS location rounded off(e.g. +120.000, -14.000). The bandwidth use is very small and battery consumption is very minimal.
