OneCap is a social deception game app, built around a simple yet highly engaging concept rooted in Gen Z culture — "Cap" means a lie, "No Cap" means the truth.
Users create a Cap — a challenge made up of 3 to 10 personal statements where exactly one is a lie — and dare their friends to spot it. The platform combines the viral appeal of social storytelling with the psychology of deception, creating a game loop that keeps users coming back daily.
Beyond 1-on-1 challenges, OneCap also features a public community feed and a live real-time multiplayer game mode, making it suitable for casual play with friends, social discovery, and party-style group games.
