# GPS Race Timer vs Revline

The clearest difference is rating: GPS Race Timer at 4.5 against Revline's 2.3. GPS Race Timer also leads on ratings volume (2.8K vs 3) and device support (3 vs 1). Revline's advantage is ads (none vs shown) and update cadence (every 2 days 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 Revline sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

GPS Race Timer holds the better App Store score, 4.5 against 2.3. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.8K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 34% of GPS Race Timer's written reviews are positive against 33% of Revline's.

GPS Race Timer ships an update every 7 months, Revline every 2 days. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
