Overall health means getting a good night's sleep as well as enough physical activity each day. Some research also says that successful weight loss depends on sleep. Several activity monitors also track sleep quality, and some allow you to track your diet as well. For sleep quality, some only assess how often you moved during the night, while the MotionX app and Jawbone UP also assess deep sleep vs. light sleep. Most also have alarms to wake you up.
The Basis is worn as a wristwatch and has several sensors on the skin side of the watch that measure heart rate, perspiration and skin temperature in addition to the motion-detecting accelerometer. It really knows when you are sleeping and automatically records sleep episodes.
Jawbone UP integrates the excellent MotionX sleep detection technology. It's a wristband activity monitor that plugs into the headphone jack of your iOS device to upload data to an app. The UP 24 syncs to iOS phones with Bluetooth Smart.
This practically-free app might be all you need, if you have an iPhone and you carry it with you all day and are willing to sleep with it at night. It provides the brains behind the Jawbone UP's sleep analysis, and you can use it as an all-day pedometer and track individual workouts.
The BodyMedia FIT system is a full-fledged lifestyle monitor -- activity, diet-tracking, and sleep, with very detailed data about each. You wear the armband monitor day and night. The LINK version of the band communicates activity data with phone apps via Bluetooth 2.0, but you have to use the USB connection to a computer to upload your sleep data.
Fitbit One, Flex and Force, as well as the older models can be used to track your sleep quality. The Fitbit Zip does not have that capability. Fitbits uploads wirelessly to a computer via a USB dongle or via a mobile app.
The Withings Pulse syncs only with mobile devices, both Android and iOS, although you can view your data online as well. It tracks steps, distance, calories burned, sleep quality and has a pulse reader.
The Misfit Shine is a sleek activity monitor you can wear on a clasp or wristband. It is purely mobile-compatible via Bluetooth 4.0.
The Polar Loop wristband activity monitor tracks sleep time as well as activity.
