Verdict
The clearest difference is rating: IMSA at 4.1 against Sonoma Raceway's 2.7. IMSA also leads on ratings volume (69 vs 15). Sonoma Raceway's advantage is update cadence (fortnightly vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
IMSA holds the better App Store score, 4.1 against 2.7. Both are backed by a comparable volume of ratings — 15 and 69 respectively. Written reviews complicate that: 33% of Sonoma Raceway's written reviews are positive against 28% of IMSA's, so the app with the better star average is not the one people write more warmly about.
Sonoma Raceway ships an update fortnightly, IMSA every 2 months. The most recent releases landed on September 16, 2026 and September 24, 2026 respectively.
