Manual training recording with the device
This update brings a new way to record your training sessions. In addition to the device’s automatic training detection and recording via the Flow app, you can now manually record training sessions directly on your device. When recording with the device, you’ll need to start and stop the session manually using the Flow app, but you won’t need to carry your phone with you during the workout. Once started, the recording will be handled entirely by the device. For more information about the training features of Polar 360, see Training with Polar 360 in the user manual.

Automatic Training Detection
Automatic Training Detection enables your Polar 360 to detect and record workouts automatically—no need to manually start or stop a session.
When enabled, your device begins recording once it detects elevated heart rate and activity levels. The data is then automatically synced to the Flow app when your phone is within Bluetooth range. This feature ensures your training is tracked even if you forget to start it manually—and you don’t need to carry your phone during the session. You can focus fully on your training while your device handles the tracking in the background. For more information, see Automatic Training Detection in the user manual.
Sleepwise™ guide to daytime alertness
The SleepWise feature is now available in the Flow app for Polar 360 users. SleepWise gives you daily Boost from sleep forecasts on how your recent sleep contributes to your daytime alertness level and readiness to perform. For more information on the feature, see Polar Sleepwise™.
Inactivity alerts via Flow app
Your Polar 360 detects if you’ve been inactive for too long during the day and reminds you to move to help reduce the negative effects of prolonged inactivity on your health. Inactivity alerts are sent via the Flow app.
You can turn inactivity alerts on or off in the Flow app device settings. To receive these alerts, ensure that notifications are allowed for the Flow app in your phone settings and that the app is running at least in the background. For more information, see 24/7 Activity tracking in the user manual.
