# Fill Up Tracker vs GPS Race Timer

The clearest difference is rating: GPS Race Timer at 4.5 against Fill Up Tracker's 2.9. GPS Race Timer also leads on ratings volume (2.7K vs 11). Fill Up Tracker's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. GPS Race Timer sells 1 one-off in-app purchase. Fill Up Tracker asks for nothing beyond the download.

GPS Race Timer holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 48% of Fill Up Tracker's written reviews are positive against 35% of GPS Race Timer's, so the app with the better star average is not the one people write more warmly about.

Fill Up Tracker ships an update every 3 months, GPS Race Timer every 7 months. The most recent releases landed on June 1, 2026 and September 25, 2026 respectively.
