Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
