You can now easily keep track of whether or not you’re fit to get behind the wheel by simply glancing at your Apple Watch! BACtrack Skyn is the first-ever wearable alcohol monitor that lets you check your blood alcohol content from your wrist on the go, it is a small sensor that can be worn as a standalone wearable, or as an Apple Watch band that syncs seamlessly with your iPhone too. The app that connects to either device offers powerful and actionable data. For instance, a user can learn when they’re approaching higher alcohol levels and slow down or stop their drinking. Best of all, there’s no need to use a breathalyzer.
