# LapLogger vs iOBD2

The clearest difference is rating: iOBD2 at 4.0 against LapLogger's 3.5. iOBD2 also leads on ratings volume (19 vs 2) and iOS requirement (4.3 vs 9). On price, review sentiment, update cadence and ads there is nothing between them.

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

iOBD2 holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: iOBD2 has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 33% of LapLogger's written reviews are positive against 29% of iOBD2's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 12, 2026 and September 21, 2026 respectively.
