+ * ALARM THERMOMETER
+ *
+ * This watch face shows the current temperature in degrees Celsius. Press and
+ * hold the alarm button to toggle between Celsius and Fahrenheit. Press and
+ * release the alarm button to start a "timer". The watch will sound an alarm
+ * when the temperature remains constant for at least 30 seconds and the
+ * temperature will stop updating until you press the alarm button. You can
+ * cancel the alarm by pressing the button again. If the temperature doesn't
+ * remain constant until the low energy timeout is reached, the alarm will stop.
+ * This is useful to measure e.g. the room temperature. If you lay off your
+ * watch from your wrist, it will take some time until it cools down, and will
+ * notify you when the measurement is constant enough.
+ * THIS WATCH FACE IS NOT INTENDED TO DIAGNOSE, TREAT, CURE OR PREVENT ANY
+ * DISEASE.
