# ECU Connect vs GPS Race Timer

The clearest difference is in-app purchases: ECU Connect at none against GPS Race Timer's 1. ECU Connect also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). GPS Race Timer's advantage is rating (4.5 vs 4.0) and ratings volume (2.7K vs 87). 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. ECU Connect asks for nothing beyond the download.

GPS Race Timer holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 87, so its average is the more settled of the two. Written reviews complicate that: 63% of ECU Connect'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.

ECU Connect ships an update every 3 weeks, GPS Race Timer every 7 months. The most recent releases landed on September 17, 2026 and September 20, 2026 respectively.
