About Not Your Phone: Mystery

She slides her phone across the table. "Please. I need to know the truth about my mother." The moment the lock screen opens, you step into someone else's life. Not Your Phone is a mystery you solve by reading a phone that isn't yours. Messages, photos, call logs, the calendar, maps — and the folder of things they thought they had deleted. Everything a person never meant to show anyone is still sitting there, in order, waiting. You answer the client's questions one at a time, and with every answer you get closer to something you might rather not know. HOW IT PLAYS - A phone you actually operate, app by app - Cross-reference clues between apps to place the truth - One question at a time, answered in your own words - Stuck? Hints move you forward without solving it for you WHAT'S INSIDE - Three complete cases in English, free from start to finish - 15 to 40 minutes per case — a commute, or the last hour of a night - Every story is original fiction, written for this app - More cases are being translated into English now FOR PEOPLE WHO - Read for the foreshadowing and the second-pass reread - Play escape rooms and detective adventures - Have always been a little too curious about other people Whether you look is up to you. But once you know, you cannot unknow it. -- Not Your Phone Pro (yearly or one-time) unlocks the full library as more stories arrive in English. The yearly plan renews automatically; manage or cancel any time in your Apple ID settings. Terms: https://notyourphone.app/en/terms Privacy: https://notyourphone.app/en/privacy
