A simple and easy to use odometer. GPS Odometer only does one thing, and does it well: measure distance traveled. Includes run in background capability. Ideal for almost anything that requires measuring outdoor distance traveled such as walking, running, driving, hiking, etc. Note that GPS does not work well under a roof. For best results, use outdoors. Benefits of the paid version: - Lock screen Widget and Notifications that can be customized to display the information that you want to see. - Landscape and splitscreen support. - Ability to have multiple trips. Each trip can be stopped and started independently. - Receive notifications while the application is closed at distance intervals of your choosing. - Custom distance unit for each trip. - Save trips to optionally restore later or for your own records. Displays: - Distance - Time elapsed - Speed (average or current) - Displacement (straight line distance from your starting point). This can be hidden. Distance units include: - Kilometers - Miles - Nautical miles - Meters - Feet Speed units include: - Kilometers per hour - Miles per hour - Nautical miles per hour - Meters per second - Feet per second Other features: - Large font adjustable display. - Home screen and lock screen widgets. - Accurate to within 1 percent when compared to most car odometers under normal driving conditions. - Approximates distance traveled in some GPS dead spots (such as driving through a tunnel) by adding the as-a-bird flies distance to your trip. Please also note: - GPS Odometer does run in the background if you leave it running. Be sure to pause the trip when you are finished or battery life will be negatively affected. The timer stops when the trip is paused. Please visit the web page for more details.

Verdict
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 (13K vs 26). GPS Odometer Pro's advantage is in-app purchases (none vs 10) and chart position (#106 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 10 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 13K 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 November 7, 2026 and November 6, 2026 respectively.
