The Compass widget allows you to quickly check your direction. The red end of the
compass needle points to north. Tapping the widget opens the compass in the
Navigation view. The compass must be calibrated before the widget can be used. You
can add the widget to the watch face in the Watch face settings.
Vertical speed & VAM
Vertical speed
Vertical speed is an instant, real-time measurement of ascents and descents, used to calculate how many meters or feet
you ascend or descend per minute, taking only altitude into account. It provides insight into your current training intensity
during climbs and can be used the same way as speed or power on level ground. To view the vertical speed during training
sessions, you need to add it to the training views of the sports profiles you wish to view it in.
Vertical speed (m/min) or (ft/min)
Ascent speed (VAM)
VAM is a metric that measures how quickly you ascend while cycling. It is expressed in vertical meters per hour (m/h). VAM
measures your average ascent speed both during a 30-second window and since the start of a lap. VAM measured during
a 30-second window (VAM, 30s) gives you an idea of how many meters you would climb in an hour if you maintained your
current pace. This information can be used to monitor your climbing performance and estimate remaining climb time.
Lap Ascent Speed (Lap VAM) shows the average ascent for the current lap. By starting a lap at the beginning of a climb,
you can track climb-specific performance metrics. Lap VAM also allows you to measure average ascent speed in intervals
during a long continuous climb. While Lap VAM provides a good measure of overall climb performance, it doesn't respond
quickly to momentary variations in intensity. To understand how momentary intensity relates to average intensity during
long climbs, you can compare ascent speed (VAM, 30s) and lap ascent speed (Lap VAM) side by side. To view these
metrics during training sessions, you need to add them to the training views of the sports profiles you wish to view them in.
VAM, 30s (m/h)

Adding Vertical speed and VAM to a Training View
Choose the data you want to view during your sessions by customizing your training views in the sports profile settings in
the Polar Flow app or web service. Vertical speed and VAM are currently available in the following sport profiles:
