The Good The S+ by ResMed can accurately track your sleep without a wristband or a mattress pad. The app (Android and iOS) offers detailed information each day on your sleep habits and provides feedback to help improve your sleep.
The Bad Sleep tracking isn't automatic and the device is expensive for something that only tracks your nighttime activities. The tracker can also be confused by someone else sharing the bed or if you move out of range of the sensor.
The Bottom Line The S+ offers accurate tracking and insightful sleep data that any insomniac will appreciate.
A wireless tracker with the goal of improving your sleep
I'm a terrible sleeper. I know this because almost all of the activity trackers I have tested over the past few months include some form of sleep tracking and they have told me that I am a terrible sleeper. I toss and turn throughout the night and wake up frequently. This isn't news to me. I've had trouble sleeping since I was a child.
All of these trackers could tell me different metrics about my sleep, but none of them offered feedback on how to improve my sleep. That's where the S+ from ResMed comes into play. In addition to tracking your sleep each night, this wireless bedside tracker provides daily tips and insight to help improve your sleep habits.
The S+ is available for $150 in the US. It's pricey considering it only tracks sleep, especially since you can buy aor for both activity and sleep tracking, for cheaper.
