+ * 1. main.c configures the watch
+ * 2. main.c calls your app_init() function.
+ * - You may wish to enable some functionality and peripherals here.
+ * - You should definitely set up some wake-up sources here.
+ * 3. main.c calls your app_loop() function.
+ * - Run code and update your UI here.
+ * 4. main.c calls your app_prepare_for_sleep() function.
+ * - Consider resetting any state that was set in your wakeup callback here.
+ * - You may also want to disable / depower external sensors or peripherals here.
+ * 5. main.c enters the STANDBY sleep mode.
+ * - No user code will run, and the watch will enter a low power mode.
+ * - The watch will remain in this state until something from (2) wakes it.
+ * 6. main.c calls your app_wake_from_sleep() function.
+ * - You may wish to re-enable any peripherals you disabled.
+ * - After this, execution resumes at step (3).
