# GPS Race Timer vs TunerView

The clearest difference is rating: GPS Race Timer at 4.5 against TunerView's 3.1. GPS Race Timer also leads on ratings volume (2.7K vs 40). TunerView's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 7 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. GPS Race Timer sells 1 one-off in-app purchase and TunerView sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

GPS Race Timer holds the better App Store score, 4.5 against 3.1. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 40, so its average is the more settled of the two. Written reviews complicate that: 35% of GPS Race Timer's written reviews are positive against 40% of TunerView's, so the app with the better star average is not the one people write more warmly about.

GPS Race Timer ships an update every 7 months, TunerView every 6 weeks. The most recent releases landed on September 20, 2026 and August 31, 2026 respectively.
