Ray versus Polar 360
Polar 360 is a platform businesses build products on. Ray is a tracker you can buy.
Polar 360 isn't sold to consumers directly. It's a screen-free sensor that companies license to build their own wearable programs, so the app, price and subscription all depend on the partner that provides it. If you're comparing it to Ray as a shopper, the real question is whether you're getting a Polar 360 through an employer or service, or buying a tracker for yourself.
The short answer
Consider Polar 360 if you're evaluating a wearable program for a business, or you're being offered one by a partner. Choose Ray if you want a complete consumer tracker you buy once, with no subscription and no charging.
Polar 360 is an active business-to-business sensor platform, not a direct-to-consumer tracker.
Polar 360 status: Available through partners.
Side by side
Specs are manufacturer claims and US pricing snapshots, not lab-test results. A blank promise is less useful than a clear tradeoff, so we keep this list deliberately practical.
