(Pocket-lint) - Polar has announced that its users will now be able to integrate their activity tracking directly with the MyFitnessPal app.

MyFitnessPal is useful for tracking daily diet, including calorie intake thanks to its huge food database that works via a scan of a barcode using a smartphone. Until now Polar data from its activity trackers and watches was separate. Now calories consumed can be measured as well as those burned allowing it all to be balanced out all in one place.

The update has come to the latest Polar Flow app version for iOS. Flow 2.3 is now compatible with MyFitnessPal and Polar says it will be moving this functionality to the Android version of its app also. When that will roll out isn't clear at this stage.

Users will be required to use the MyFitnessPal app, as usual, to log food intake. The Flow app will record activity via trackers like the A300. This can be synced to pull data in from MyFitnessPal, as well as the wearable, so it's all accessible in a one-stop-shop spot right there in the Flow app.

The Polar Flow app 2.3 is available now to download for iOS devices. Expect to hear more on the Android update in due course.
