Sleep well, live well
Discover the secrets of good sleep
A sleep lab on your wrist
Great sleep data is no use if it is too complicated to understand - that’s why our algorithms do the work for you. You can check the length and depth of your sleep, total sleep hours, and comparisons of your sleep quality over time, all laid out in clear graphs right in the app.
The science behind the magic
Even though sleep is complicated, our tracking system is easy to understand. Our watches automatically track motion and heart rate, and these two things combined let it accurately record sleep quality and depth. All you have to do is wear your watch, and our software does the rest.
