A compatible OBD adapter is required. Premium-level adapters supported (best speed and stability): - OBDLink MX+; - OBDLink CX; - vLinker MC+. Entry-level adapters supported (moderate speed, good stability): - Vgate iCar Pro Bluetooth 4.0 (BLE). Other adapters supported: - Viecar Bluetooth 4.0 (BLE), Vgate iCar Pro WiFi, Veepeak OBDCheck BLE+, KONNWEI. We do NOT support the majority of cheap ELM327 v2.1 clones.

Verdict
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.
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. ActiveOBD sells 1 in-app purchase, starting at $4.99 per month. ezOBD asks for nothing beyond the download.
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.
ezOBD ships an update monthly, ActiveOBD every 3 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
