In 'Whose Phone Is This, Anyway?', players assume the role of a snarky amateur detective who finds a mysterious smartphone on the subway. Instead of merely trying to return it, the detective delves into the digital life of its owner using a unique app that unveils secrets, tracks down relationships, and reveals dramatic events. As the detective converses with quirky characters, uncovers juicy scandals, and navigates a web of unexpected twists, the player must piece together the real story behind the phone and its enigmatic owner within a limited timeframe, all while keeping their witty or sarcastic dialogue flowing.
