What's the best iOS app for quick social deduction games with friends?

Imposter Game — Who is Spy? is designed specifically for social deduction gameplay in casual settings. The app streamlines the classic 'spy' party game format where players receive words—all identical except for one player who gets a different word. Through questioning and discussion, players must identify the imposter before time runs out. Each round typically lasts 5-10 minutes, making it ideal for quick sessions between other activities or as an icebreaker at social gatherings. The interface includes timer settings, word categories, and player elimination voting, all presented in a clean, accessible layout. Reviews indicate the straightforward mechanics help new players understand the game quickly, with many users praising how it maintains engagement across different group sizes. Some players note the word library could be more extensive, and the basic visual presentation lacks the polish of premium party games. However, the core gameplay remains solid, with reliable performance across iOS devices and no complicated setup required. For impromptu game nights or social events where elaborate preparation isn't practical, this app provides consistent entertainment value.
