# Roblox vs Kart Rush

The clearest difference is in-app purchases: Kart Rush at none against Roblox's 4. Kart Rush also leads on rating (4.8 vs 4.5) and iOS requirement (10.0 vs 14.0). Roblox's advantage is ads (none vs shown) and update cadence (every 6 days vs every 2 months). On price and device support there is nothing between them.

Both are free to download. Roblox sells 4 in-app purchases, starting at $4.99 per month. Kart Rush asks for nothing beyond the download.

Kart Rush holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Roblox has 21M ratings behind it against 21, so its average is the more settled of the two.

Roblox ships an update every 6 days, Kart Rush every 2 months. The most recent releases landed on November 13, 2026 and November 3, 2026 respectively.
