# BT1 vs OBD Home

The clearest difference is rating: OBD Home at 2.9 against BT1's 2.4. OBD Home also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (50 vs 14). BT1's advantage is review sentiment (48% vs 32%) and iOS requirement (10.0 vs 13). 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.

OBD Home holds the better App Store score, 2.9 against 2.4. Both are backed by a comparable volume of ratings — 14 and 50 respectively. Written reviews complicate that: 48% of BT1's written reviews are positive against 32% of OBD Home's, so the app with the better star average is not the one people write more warmly about.

BT1 ships an update every 4 months, OBD Home every 3 weeks. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
