For Microsoft Band 2 wearers, Fitbit fitness trackers are now becoming a real viable alternative. As Fitbit developers inch closer to bringing the full support of the services notification suite to Windows phones, users are also getting newly announced features called Sleep Stages and Sleep insights within the app.
The new features are similar to what Microsoft's combined Health app and fitness band provided wearers.
Microsoft kept much of the science behind its Band's ability to track sleep in shrouds of algorithmic secrecy, Fitbit explains that Sleep Stages tracks sleep through series of factors. Among the factors that play into Sleep Stages is heart rate variability and machine learning to produce reports of light sleep, deep sleep, REM and awake times.
Sleep Insights attempts to catalog the collected sleep data and spit our real world trends, suggestions and diet and exercise routines based on the numbers.
While many still don't understand the science behind sleep tracking, it remains a novel feature for fitness trackers to provide. The update should be rolling out to Windows 10 devices today.
