There is a new sleep optimizing Sleeptracker watch on the market. Innovative Sleep Solutions has updated their sleep watch with the Sleeptracker Pro.

Digital Reviews has tested the new Sleptracker Pro and published a review.
Quote from the review: "Apart from the new look, the new Pro model improves upon the original by increasing the sleep window (more on this later) to up to 90 minutes as well as increasing the sleep data collection from 8 hours to 12. The SLEEPTRACKER Pro also features a vibrating alarm and is able to transfer your sleeping data to your PC for review and archiving of sleeping patterns."
