Verdict
The clearest difference is rating: OBD2 Scanner at 4.6 against MAXOBD's 2.4. OBD2 Scanner also leads on ratings volume (974 vs 7). MAXOBD's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. OBD2 Scanner sells 6 in-app purchases, starting at $6.99 per 7 days. MAXOBD asks for nothing beyond the download.
OBD2 Scanner holds the better App Store score, 4.6 against 2.4. That said, the two scores are not equally well evidenced: OBD2 Scanner has 974 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 23% of OBD2 Scanner's written reviews are positive against 29% of MAXOBD's, so the app with the better star average is not the one people write more warmly about.
OBD2 Scanner ships an update monthly, MAXOBD every 3 weeks. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
