The new Sleeptracker Pro takes the original “sleep watch” concept and adds a new software component, allowing you to download your “sleep history” to a PC and track how well you’ve snoozed over time. The new Sleeptracker Pro watch has an updated look, too, although it’s still a bit too goofy to be worn all day.
The reviews for the original Sleeptracker were surprisingly positive. Many people found that the Sleeptracker, which uses an accelerometer to gauge what sleep state you might be in and wakes you at the optimum moment of restfulness, actually did a pretty great job.
The Sleeptracker Pro system is $180, or $30 more than the vanilla Sleeptracker.
