"Can I just take a quick look?" The second the lock screen opens, there is no going back. Three full cases, free, in English.
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.
