Why BACtrack
Police-grade accuracy. Smartphone-easy.
BACtrack was the first company ever to receive FDA 510(k) clearance for a consumer breathalyzer back in 2004 — and it remains the gold standard for at-home BAC measurement.
BACtrack's Xtend® Fuel Cell sensor — engineered from technology used in experimental vehicle fuel mixing — has been independently tested side-by-side with the police-grade DataMaster ($7,000 unit) and closely mirrored its readings below 0.08% BAC.
01
Professional fuel cell
Xtend® fuel cell technology, the same kind used by US hospitals, clinics, and law enforcement. Detects ethanol specifically — no false positives from acetone or other vapors.
02
ZeroLine® intelligence
BACtrack invented the smartphone breathalyzer category in 2013. ZeroLine® projects when your BAC will hit 0.00% so you can decide — and call a ride straight from the app.
03
Trusted globally
Used by Kaiser Permanente, MADD, and leading US universities. Sold in 25 countries. Won the NIH Wearable Alcohol Biosensor Challenge in 2016.
Proven in the field
162 tests. Match the police.
In rigorous controlled studies, BACtrack was tested side-by-side with the DataMaster — the court-admissible breathalyzer used by US police — across 162 individual tests on 8 subjects over 12 hours. The result: BACtrack Mobile Pro almost perfectly mirrored the reference unit.
"BACtrack is the most accurate breathalyzer commercially available" — NBC, CBS affiliates and Car & Driver independent tests.
