The market is filled with many varieties of sleep trackers, but none are quite like the 'Opter Sleep' system. Rather than just track your sleep, the 'Opter Sleep' system is designed to help you live a better life overall. The unit stays on your bed and has no wires and never requires recharging to ensure it's always ready to go. The unit automatically tracks your sleep and can offer enhanced metrics regarding your time in bed.
The 'Opter Sleep' system can also be used in conjunction with other apps and is easily synced; simply having your phone in the same room allows for data backups to occur.
The 'Opter Sleep' is currently being funded on Kickstarter and is surely one of the more lifestyle-focused sleep trackers on the market.
