# BACtrack vs Shaterian

The clearest difference is review sentiment: Shaterian at 100% against BACtrack's 27%. Shaterian also leads on rating (5.0 vs 4.2) and update cadence (every 2 days vs every 2 weeks). BACtrack's advantage is ratings volume (1.5K vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BACtrack sells 1 in-app purchase, starting at $39.99 per year and Shaterian sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Shaterian holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: BACtrack has 1.5K ratings behind it against 1, 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 100% of Shaterian's.
