In 'Whose Phone Is This, Anyway?', you play as an amateur detective who stumbles upon a mysterious smartphone left behind in a crowded coffee shop. The phone contains a series of bizarre texts, cryptic photos, and ominous voicemails that suggest the owner is pulled into a web of intrigue and danger. Your task is to piece together clues by interacting with the phone's apps and contacting various characters through it. Each choice leads you down a different path, revealing the secret behind the phone, and possibly involving you in a deeper conspiracy. Use your wit and resourcefulness to uncover secrets, avoid confrontations, and ultimately decide the fate of the phone’s original owner—all while dodging unhelpful and eccentric coworkers at your detective agency.
