Polar has released its OS6 software update, which allows users to view trend graphs and log weight data directly on their smartwatches. The update aims to reduce the necessity of relying on the smartphone application for common health metrics.
Why it matters
By moving tracking features from a smartphone to the wrist, this update simplifies how users monitor health data during daily activities. The change prioritizes faster access to personal biometrics, making consistent health logging more convenient.
The OS6 update introduces nine new on-watch trend graphs and adds functionality for direct weight entry across six compatible device models. Users can also view up to seven previous weight entries directly on the watch interface.

The update is installed by syncing the watch with the Polar Flow mobile application.

Additionally, an optional charging limit of 80 percent has been introduced to help manage long-term battery performance.
