Won’t pair with H7!
This ended up working well with my iPhone 5, and I got a second H7 as well as buying the in-app package. However, in switching to an iPhone 6s (iOS 9.2.1), the Polar Beat app is not pairing with the H7. The H7 itself works fine with gym equipment, it pairs with the iPhone itself, and it works with another app that I downloaded - so, the problem is with Polar Beat itself. I reported the problem to Polar customer service, and haven’t heard anything.
