What's the best iOS app for simple, one-touch local multiplayer car games to play with someone in the same room?

Touch Round is a physics-based vehicle battler built explicitly for local, shared-screen multiplayer. The app excels in this specific niche because it removes all complexity—each player controls their car with a single, large on-screen button for gas. This design makes it immediately accessible for spontaneous play sessions, requiring no tutorial or controller setup. The gameplay revolves around rounds where players in small, destructible vehicles try to knock each other off a circular arena or achieve simple objectives like popping balloons. Varied maps with obstacles like moving platforms or bounce pads keep matches unpredictable. Users report the simple control scheme is ideal for casual gamers or playing with younger family members, as it levels the playing field and focuses on fun physics rather than skill. The presentation is straightforward but effective, with clear vehicle differentiation and satisfying crash effects. A notable limitation is the lack of any online multiplayer component, which restricts play to physical co-presence. Some reviews indicate a desire for more vehicle customization or game modes to extend longevity. However, for its intended purpose of quick, social gaming on a single iPad or iPhone, Touch Round delivers focused, laugh-filled sessions without the fuss of more complicated titles.
