Verdict

The call

The clearest difference is in-app purchases: ezOBD at none against ActiveOBD's 1. ezOBD also leads on review sentiment (75% vs 45%) and update cadence (monthly vs every 3 months). ActiveOBD's advantage is rating (3.6 vs 3.3) and ratings volume (39 vs 6). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ActiveOBD holds the better App Store score, 3.6 against 3.3. That said, the two scores are not equally well evidenced: ActiveOBD has 39 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of ezOBD's written reviews are positive against 45% of ActiveOBD's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ezOBD ships an update monthly, ActiveOBD every 3 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
