# IMSA vs Rally4NOW

The clearest difference is review sentiment: Rally4NOW at 83% against IMSA's 28%. Rally4NOW also leads on rating (5.0 vs 4.1) and ads (none vs shown). IMSA's advantage is ratings volume (69 vs 1). On price, update cadence, 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.

Rally4NOW holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: IMSA has 69 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 28% of IMSA's written reviews are positive against 83% of Rally4NOW's.

IMSA ships an update every 2 months, Rally4NOW every 5 weeks. The most recent releases landed on October 12, 2026 and October 16, 2026 respectively.
