A DETECTIVE GAME FOR IPHONE
A phone found on a train platform. A mystery inside.
Unlock a stranger's phone, read their messages, search their photos, reply to the people who text them… and take the investigation into the real world.
Free to download · no ads · no subscription · in French for now
No board, no controller: everything happens inside a phone that isn't yours, and a little beyond it.
Messages, photos, emails, calls, calendar, voice memos: any detail can be a clue. First, you have to find the passcode.
While you investigate, the owner's family keeps texting. You choose what to answer, and they remember it.
Turn it like a key to open a station locker, blow on an old programme to clear away the dust.
Real websites to visit, a real email address to write to. And always a nudge if you get stuck.
The phone has its own system, its own apps and its own secrets. The case notebook is made of paper. Screenshots from the French version.




Grandpa, a retired music-hall magician, launches the last great game of his life: a treasure hunt by text message for his grandchildren. The winner will inherit "the most precious thing in the family".
Except Camille lost their phone running for a train. You found it. And Grandpa only sends his riddles to that number.
The Olympia in 1987, Grandpa's video message, and a phone sliding onto platform 7. In French.
Each story has its own theme and five chapters. The first one is free: you play, then you decide.
More stories, with other themes, are on their way.
A detective and puzzle game for iPhone. You find a stranger's phone and investigate inside it: a passcode to find, messages to read, photos to search, characters who text you. Some riddles are even solved off the screen.
It feels like one: you find codes, cross-check clues and open what is locked. But everything happens inside a phone, and each story tells a real plot, in five chapters.
Each story has five chapters, and a chapter takes about 45 minutes to an hour. You can stop whenever you like: the game picks up where you left off.
The game is free to download and the first chapter of every story is free. The full story is then bought once: €4.99 for Grandpa's Treasure Hunt. No ads, no subscription.
iPhone, with iOS 17 or later. There is no Android version for now.
The game is in French for now. The English version is in the works.
The stories are designed for players aged about 12 and up: mystery and humour, no violence.
A cousin of the phone's owner texts you nudges, in three levels: point you, guide you, give it away. No riddle leaves you stuck.
Not for most of it. A few riddles invite you to visit a website or send an email; offline, a nudge gives you the answer.
No. The “Restaurer l'achat” (restore purchase) button in the game brings it back on any device signed in with the same Apple Account. Family Sharing is on.
Nothing leaves your phone: no account, no ads, no tracking. The microphone is only used to detect a breath, when you ask for it, and nothing is recorded. Privacy policy.
Soon on the App Store. More stories, with other themes, will follow.
