Smart notifications (Android)

The smart notifications feature allows you to get alerts about incoming calls, messages and notifications from apps onto your Polar device. You’ll get the same notifications on your Polar device that you get on your phone screen. Please note that when heart rate training with your A370, you can’t receive any notifications.

  • Make sure you have Android version 5.0 or newer on your phone.

  • To use the Smart Notifications feature you need to have the Polar Flow mobile app for Android, and your A370 needs to be paired with the app.

  • For the Smart Notifications feature to work, Polar Flow app must be running on your phone.

  • Please note that when the Smart Notifications feature is on, the battery of your Polar device and phone will run out faster because Bluetooth is continuously on.

We have verified the functionality with some of the most common phone models, like Samsung Galaxy S5, Samsung Galaxy S6, Nexus 5, LG G4, Sony Xperia Z3. There might be differences in the functionality with other phone models which support Android 5.0.

Do not disturb setting in Polar Flow app

Do not disturb setting disables the display from turning on from your wrist movement, and lets you rest better in dark conditions, like in the bedroom for example.

If you want to disable notification alerts for certain hours of the day, set Do not disturb on in the Polar Flow mobile app. When it's on, you won't receive any notification alerts during the time period you've set. Do not disturb is set on by default, and the time period is 10 pm – 7 am.

Change the Do not disturb setting as follows:

  1. Open the Polar Flow mobile app.
  2. Go to > Devices and your A370 page if you have more than one Polar device.
  3. Toggle Do not disturb on or off, and set the start and end time for it. The Do not disturb setting is visible when the Smart notifications setting is on.
  4. Sync your A370 with the mobile app by pressing and holding on the button of your A370.

You can disable the notification alerts right on your A370 as follows:

  2. Tap the Do not disturb icon:

To enable the notifications alerts, repeat the steps.

Block apps

In Polar Flow app you can block notifications from certain apps. As soon as you’ve received the first notification from an app to your A370, the app will be listed in > Devices > Block apps and you can block it if you wish.

Phone settings

To be able to receive notifications from your phone on your A370, you first need to enable notifications on the mobile apps from which you want to receive them. You can do this either via the mobile app’s settings or via your Android phone’s App notifications settings. See the user manual of your phone for further information on App notifications settings.

Then Polar Flow app has to have permission to read the notifications from your phone. You have to give Polar Flow app access to your phone notifications (i.e. enable notifications in the Polar Flow app). Polar Flow app guides you to give access when needed.


When getting an alert, your Polar device will discreetly notify you by vibrating. When receiving a call, you can choose to answer, silence or decline it. Silencing just silences your Polar device, it won’t silence your phone. If a noti­fication arrives during a call alert, it will not be shown.

You will not receive any notifications during training sessions.

Dismiss Notifications

Notifications can be dismissed manually or by timeout. Manually dismissing the notification also dismisses it from your phone screen, but timeout just removes it from your Polar device, and it will still be visible on your phone.

To dismiss notifications from the display:

  • Manually: Press the side button

    Timeout: The notification will disappear after 30 seconds if you do not dismiss it manually

The Smart Notifications Feature Works via Bluetooth Connection

The Bluetooth connection and the Smart Notifications feature work between your A370 and your phone when they are in the line of sight and within the range of 5 m /16 ft from each other. If your A370 is out of range for less than two hours, your phone restores the connection automatically within 15 minutes when your A370 returns to the range area.

If your A370 is out of range for more than two hours, restore the connection by pressing and holding the button on your A370.
