Sleep tracking with Apple Watch is a great way to gain new insight into your sleeping habits and trends over time. Apple is apparently working on its own sleep tracking features for Apple Watch, but those features aren’t available just yet. In the absence of a first-party solution for Apple Watch sleep tracking, a handful of incredibly powerful third-party apps have come to the App Store.

My wife is wanting to get more info on her sleep tracking using the Apple Watch v3. Does anyone use or recommend any of these apps or any that aren’t on the list?
