# Zero4Racer PRO vs Revving

The clearest difference is rating: Revving at 5.0 against Zero4Racer PRO's 3.1. Zero4Racer PRO's advantage is ratings volume (35 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zero4Racer PRO sells 2 one-off in-app purchases and Revving sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Revving holds the better App Store score, 5.0 against 3.1. That said, the two scores are not equally well evidenced: Zero4Racer PRO has 35 ratings behind it against 2, so its average is the more settled of the two.

Zero4Racer PRO ships an update every 2 weeks, Revving every 9 days. Both last shipped on November 10, 2026.
