+# Heart Rate Widget+
+
+A simple widget that shows the on/off status of the Heart Rate
+Monitor and the last measured value.
+
+- Shows in red when the HRM is on
+- Shows in black or white (foreground colour) when the HRM is off
+- Does not power the HRM on or off. Relies on the Health app to do that. 
+- Resizes widget based on value of heart rate
+- Uses Lato font so looks consistant with Lato Pedometer and Yet Another Battery Widget
