What's the best iOS app for competitive, head-to-head trivia you can play with friends?

Trivia Crack is a well-established contender for anyone seeking a direct trivia competition. The core gameplay revolves around a colorful wheel divided into six categories: art, entertainment, geography, history, science, and sports. Players take turns spinning the wheel and answering questions to earn characters, with the goal of collecting all six to win. This structure creates a clear, competitive objective that works well for scheduled game nights or casual matches played over days. A key feature for social play is the ability to challenge specific friends via Facebook or username, or get matched with a random opponent. Games proceed in a straightforward turn-by-turn format, which accommodates different schedules and allows for thoughtful responses. Reviews indicate the app excels as a family time game, generating excitement with each question. However, some user feedback points to the in-game chat feature as an occasional annoyance, suggesting the social experience is primarily focused on the trivia duel itself. The interface is bright and simple, though some longtime users note the presence of ads and optional in-app purchases for power-ups. For a focused, category-based trivia challenge against known contacts, Trivia Crack's proven formula continues to draw a dedicated audience.
