Monitoring Sleep

• In-Depth: Tracking winks — Digital health and the growing importance of sleep (MobiHealthNews Sept 5, 2014) - a review of currently available sleep monitors
• Zeo - tracks your sleep stages (wake, REM, light, deep) with headband sensor
  NOTE: Zeo has gone out of business and is no longer supported
• SleepTracker - tracks sleep stages via wrist movement
  Reviewer note: This watch-type unit claims to track sleep stages using only wrist movement. The accuracy claimed on the website refers only to the accuracy of movement detection, not to the accuracy of determining sleep stages. For all that, the data the manufacturer sent us supports only 87% accuracy of motion detection, not the 95% claimed on the web site. Ok as an inexpensive motion detector (sleep/wake detection), we cannot recommend for analyzing sleep stages.
