# PROOF + vs BACtrack View Enterprise

The clearest difference is review sentiment: BACtrack View Enterprise at 100% against PROOF +'s 50%. PROOF +'s advantage is rating (4.6 vs 2.6) and update cadence (every 9 days vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PROOF + holds the better App Store score, 4.6 against 2.6. That said, the two scores are not equally well evidenced: PROOF + has 105 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 50% of PROOF +'s written reviews are positive against 100% of BACtrack View Enterprise's, so the app with the better star average is not the one people write more warmly about.

PROOF + ships an update every 9 days, BACtrack View Enterprise every 2 months. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
