Verdict
The clearest difference is rating: Rally Results at 5.0 against IMSA's 4.1. Rally Results also leads on ads (none vs shown) and monetization model (free vs ad-supported). IMSA's advantage is review sentiment (28% vs 0%) and ratings volume (70 vs 3). 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.
Rally Results holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: IMSA has 70 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 28% of IMSA's written reviews are positive against 0% of Rally Results's, so the app with the better star average is not the one people write more warmly about.
IMSA ships an update every 2 months, Rally Results every 5 weeks. The most recent releases landed on October 29, 2026 and October 16, 2026 respectively.
