The official Fitbit app for Windows and Windows 10 PC and Mobile has picked up some handy new features for tracking your sleep cycle. First announced earlier in March, Sleep Stages and Sleep Insights are now available in teh Windows app, helping you to track your sleep with more detail and accuracy.

To recap from Fitbit's original announcement, Sleep Stages is a feature that improves on Fitbit's current sleep tracking by taking more factors into account. Instead of leveraging accelerometer data only, Sleep Stages leans on machine learning algorithms and heart rate variability to give you a deeper, more accurate look into your night. The readout is represented in the Sleep Stages section of the app with graphs showing time in light sleep, deep sleep, REM sleep and awake minutes.

Sleep Insights, on the other hands, seeks to take all of your Fitbit data into account to help you spot trends affecting your sleep. Diet and exercise patterns, for example, might lead Fitbit to make suggestions on how you can change up what you eat when, or when you exercise, yo improve your sleep.

Sleep Stages should work with the new Alta HR, Blaze and Charge 2. Sleep Insights is intended to work with all trackers except the Zip. Both features are now available in the latest update to the Windows 10 app.
