# RSCHIP CHIPTUNING vs GPS Race Timer

The clearest difference is rating: RSCHIP CHIPTUNING at 5.0 against GPS Race Timer's 4.5. RSCHIP CHIPTUNING also leads on in-app purchases (none vs 1) and ads (none vs shown). GPS Race Timer's advantage is ratings volume (2.7K vs 2) and review sentiment (35% vs 25%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. GPS Race Timer sells 1 one-off in-app purchase. RSCHIP CHIPTUNING asks for nothing beyond the download.

RSCHIP CHIPTUNING holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 25% of RSCHIP CHIPTUNING'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.
