# MobiSquirt vs GPS Race Timer

The clearest difference is rating: GPS Race Timer at 4.5 against MobiSquirt's 3.0. GPS Race Timer also leads on update cadence (every 7 months vs every 41 months) and ratings volume (2.7K vs 4). MobiSquirt'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. MobiSquirt asks for nothing beyond the download.

GPS Race Timer holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of MobiSquirt'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.

MobiSquirt ships an update every 41 months, GPS Race Timer every 7 months. The most recent releases landed on July 20, 2026 and September 20, 2026 respectively.
