Meet the PROOF wearable: a smart gadget that detects alcohol through your skin and helps you make smarter decisions after drinking. It can tell you when you have reached your preset threshold or how soon you will be sober.
PROOF uses LED and vibration alerts to let you know when you have reached your drinking limit. It is powered by a 12 mAh battery that lasts up to 4 days. Its disposable cartridge ensures alcohol tracking for over 12 hours.
