Brought you by the open-source OVMS project, you can finally remotely monitor your cutting edge Electric Vehicles. The app shows you your current state of charge (SOC), door/trunk/hood status, tire pressures and temperatures (TPMS), core system temperatures (PEM, motor, and ESS/battery), and displays your car's live GPS location on the map. Although separate OVMS hardware is required for remote monitoring your vehicle, you can try out this app and see what it can offer you via the included DEMO car account. Charging station integration and information provided by Zero Carbon World (http://www.zerocarbonworld.org/open-charge-map) and the Open Charge Map project (www.openchargemap.org).

Verdict
The clearest difference is in-app purchases: Open Vehicles at none against OBD2 Car Scanner's 3. Open Vehicles also leads on review sentiment (74% vs 55%) and iOS requirement (12.0 vs 14.0). OBD2 Car Scanner's advantage is rating (4.6 vs 4.2) and ratings volume (5.2K vs 14). 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. OBD2 Car Scanner sells 3 one-off in-app purchases. Open Vehicles asks for nothing beyond the download.
OBD2 Car Scanner holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 5.2K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 74% of Open Vehicles's written reviews are positive against 55% of OBD2 Car Scanner's, so the app with the better star average is not the one people write more warmly about.
Open Vehicles ships an update every 4 months, OBD2 Car Scanner every 5 weeks. The most recent releases landed on October 21, 2026 and October 25, 2026 respectively.
