I could see some use in fitness tracking when playing a sport where you'd be asked to take off a watch (pickup basketball, for example). But that's why I think there could be a market for it - its value prop is simply that it's both extremely low profile and connected. The Oura ring is simply too expensive for me, but I think I'd pay $130 for a wearable sleep tracker that integrates with Apple Health that provided me high quality data about my sleep quality.
