Why should I update the Polar Loop software? What happens when I do that with Polar FlowSync?
To get the best out of your Polar Loop and to keep it up-to-date, we recommend always using the latest version of the firmware.
If new updates for Polar Loop are available, Polar FlowSync will automatically prompt you to update it.
When you start the update, Polar FlowSync will sync all your activity data with the Polar Flow web service first. It will then update the Polar Loop software which will erase all the activity data from the bracelet. For this reason the Polar Flow mobile app and Polar Loop may show incomplete activity data for this day, but not to worry, all your activity data is added up in the Polar Flow web service: it combines the activity data from before and after the software update.
