Which iOS app is best for a casual, quick racing game to play with family on different devices?

Mario Kart Tour is a strong candidate for casual, cross-device family racing. The app's primary appeal lies in its accessible multiplayer setup. Players can join races with friends and family worldwide using just a friend code, without requiring complex lobby systems. The touch-screen controls, featuring optional auto-accelerate and simple steering gestures, lower the skill barrier, making it easy for younger players or those less familiar with racing games to participate. Regular tours introduce new courses based on real-world cities and classic Nintendo locales, providing consistent novelty. However, the experience is heavily tied to a Nintendo Account for progress saving and multiplayer, which some users report can present initial sign-in hurdles. The free-to-play model includes a gacha-style system for unlocking drivers and vehicles, which may require patience or in-app purchases for specific favorites. For families seeking quick, recognizable racing action with minimal setup between devices, it delivers a competent and often entertaining package.
