# BACtrack vs Alcohol Sensor

The clearest difference is rating: BACtrack at 4.1 against Alcohol Sensor's 3.0. BACtrack also leads on ads (none vs shown) and ratings volume (1.4K vs 2). Alcohol Sensor's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On price and update cadence there is nothing between them.

Both are free to download. BACtrack sells 1 in-app purchase, starting at $39.99 per year. Alcohol Sensor asks for nothing beyond the download.

BACtrack holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: BACtrack has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 27% of BACtrack's written reviews are positive against 3% of Alcohol Sensor's.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 23, 2026 and August 27, 2026 respectively.
