# IMSA vs Formula E

The clearest difference is ads: Formula E at none against IMSA's shown. Formula E also leads on ratings volume (1K vs 69). On price, rating, review sentiment and update cadence there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.1 for IMSA against 4.2 for Formula E. That said, the two scores are not equally well evidenced: Formula E has 1K ratings behind it against 69, so its average is the more settled of the two. Written reviews are what separate them: 28% of IMSA's written reviews are positive against 22% of Formula E's.

IMSA ships an update every 2 months, Formula E every 3 weeks. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
