# NASCAR MOBILE vs IMSA

The clearest difference is rating: NASCAR MOBILE at 4.7 against IMSA's 4.1. NASCAR MOBILE also leads on review sentiment (63% vs 28%) and ratings volume (194K vs 69). IMSA's advantage is in-app purchases (none vs 14). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. NASCAR MOBILE sells 11 in-app purchases, starting at $2.99 per month. IMSA asks for nothing beyond the download.

NASCAR MOBILE holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: NASCAR MOBILE has 194K ratings behind it against 69, so its average is the more settled of the two. Written reviews point the same way: 63% of NASCAR MOBILE's written reviews are positive against 28% of IMSA's.

NASCAR MOBILE ships an update every 2 weeks, IMSA every 2 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
