# GPS Race Timer vs Perception

The clearest difference is rating: GPS Race Timer at 4.5 against Perception's 3.4. GPS Race Timer also leads on ratings volume (2.8K vs 13) and iOS requirement (12.2 vs 16.6). Perception's advantage is ads (none vs shown) and update cadence (every 10 days vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. GPS Race Timer sells 1 one-off in-app purchase and Perception sells 3 in-app purchases, starting at $1.99 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 3.4. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.8K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 34% of GPS Race Timer's written reviews are positive against 56% of Perception'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, Perception every 10 days. The most recent releases landed on November 2, 2026 and October 27, 2026 respectively.
