When it works it’s great.

Constant failures to sync, crashes etc take away from an otherwise useful app. Syncing with M430 has never ever been reliable through the app. Plugin via usb is great as it charges watch as well. Desktop polar flow is excellent. Please fix the glitchy iOS app. It’s the one thing that would drive me to a Garmin next purchase.

Great for training

The app and products work very well together for accurate training information. I would be great if there was a gps option was added in the next upgrade that enabled input of grid references and used bearings etc

Polar review

I’ve recently changed to a polar watch (polar vantage m) from a garmin and without a doubt I prefer the polar watch. My only problem is with the polar flow app,while the app itself isn’t bad it simply doesn’t compare to the garmin connect app. The app is complicated and it’s hard to find all the data that’s provided
