Are their products usable without web-accounts? I'm thinking about buying a watch. Also, recently I bought Polar HR10 heartrate monitor and was unpleasantly surprised by the fact their Android app is also "signup required", for practical purposes. I mean, it does let you use it offline, but I never found a way to actually export my data (I suppose it should be doable in their web-app, though). And I didn't find any alternative HR-logging app for Android that would allow me to do that, so that I could use the product I bought the way I want. Well, nobody promised me I will be able to, but I still feel kinda robbed.
