KARE in Minneapolis recently conducted a test of competing smartphone breathalyzers, pitting BACtrack Vio, Alcohoot and Breathometer against law enforcement units to see how they fared.
The video, which stars the celebrity hosts of The Power Trip Morning Show on KFAN, is interesting viewing, and shows accurate the BACtrack Vio really is.
"BACtrack had [patron] Carr at .08, the legal limit. And that was pretty close to the sheriff's official breathalyzer, which was just under that at .076."
