# OBDLink vs GPS Odometer Pro

The clearest difference is price: OBDLink at Free against GPS Odometer Pro's $4.99. OBDLink also leads on rating (4.8 vs 3.4) and ratings volume (12K vs 26). GPS Odometer Pro's advantage is in-app purchases (none vs 75) and chart position (#94 vs unranked). On review sentiment, ads and device support there is nothing between them.

OBDLink is free to download; GPS Odometer Pro costs $4.99 up front. OBDLink sells 73 one-off in-app purchases. GPS Odometer Pro asks for nothing beyond the download.

OBDLink holds the better App Store score, 4.8 against 3.4. That said, the two scores are not equally well evidenced: OBDLink has 12K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 62% of OBDLink's written reviews are positive against 67% of GPS Odometer Pro's, so the app with the better star average is not the one people write more warmly about.

OBDLink ships an update every 2 months, GPS Odometer Pro every 4 months. The most recent releases landed on October 14, 2026 and October 4, 2026 respectively.
