We access your sleep through the Healthkit integration in our iPhone app. Sleep can be entered into Healthkit from many different hardware and software, or manual entry, allowing us to support many of the popular sleep trackers.
For a more automatic and passive experience, you can get a sleep tracker for your bed. Obviously this costs money to buy, but removes the need for opening an app every night. We have been using and liking the Hello Sense—which can save sleep to Healthkit. Other sleep tracking devices that have Healthkit integrations, like Withings Aura, are also similarly supported.
Most of our sleep analysis can be seen in the Helix theme, under the brain section.
Having sleep data also makes other parts of the site more useful. For example, we can highlight when you were sleeping on your heart rate graph. Usually it is clearly much lower. If there were disturbances or you are woken up by the sun at a certain time, that becomes easy to see in the graphs.
Heart rate tracking
We highly recommend keeping your heart rate monitor on while you sleep. The resting heart rate data from while you sleep is the most relevant. Charging an Apple Watch or Fitbit does not take very long, so it is unnecessary to leave them plugged in all night.
