The maps app is getting a dark mode to make it easier on the eyes. Polar OS 5 further introduces two new watch face widgets or complications that provide insight into sleep quality from the previous night and activity from the past week. When the smartwatch is connected to a charger, it can now show the current time.

Polar OS 5 asks users after a workout how strenuous it was, while a rating from 1 to 10 helps the smartwatch adjust the next workout to the user’s performance. Additionally, Polar resolved an issue that could cause iPhone notifications to show up multiple times, and performance when zooming in the maps app has also been improved.Â
