# INDYCAR vs Detroit GP

The clearest difference is rating: INDYCAR at 4.4 against Detroit GP's 3.9. INDYCAR also leads on ratings volume (4K vs 15). Detroit GP's advantage is review sentiment (80% vs 50%) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

INDYCAR holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: INDYCAR has 4K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 50% of INDYCAR's written reviews are positive against 80% of Detroit GP's, so the app with the better star average is not the one people write more warmly about.

INDYCAR ships an update every 2 weeks, Detroit GP weekly. The most recent releases landed on October 12, 2026 and September 28, 2026 respectively.
