# ezOBD vs Viecar

The clearest difference is review sentiment: ezOBD at 75% against Viecar's 20%. ezOBD also leads on ratings volume (6 vs 1). Viecar's advantage is rating (4.0 vs 3.3). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Viecar holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: ezOBD has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of ezOBD's written reviews are positive against 20% of Viecar's, so the app with the better star average is not the one people write more warmly about.

ezOBD ships an update monthly, Viecar every 4 weeks. The most recent releases landed on October 25, 2026 and October 11, 2026 respectively.
