Someone Else's Phone Downloads & RevenueSomeone Else's Phone: Mystery · App Store

No game screen. No menus. Just a stranger's phone, and the truth hidden inside it.

Unlock it. Read the texts and chats. Dig through the photos, notes and voice memos. Answer the calls when they come. Messages keep arriving while you play, and the people on the other end think you're the owner.

Someone Else's Phone is a new kind of mystery game you play as if you were holding a real stranger's smartphone.
Every app on the phone is a clue: messages, messenger, photos, notes, mail, calendar, maps, cloud, banking, voice memos and call history.
Piece the clues together to crack passcodes, reply as if you were the owner, and work out who did it.

■ Case files
· Cheongpyeong Lake (Thriller · Missing person) — A designer vanished by the lake. Now her phone has arrived at your door in a parcel. The note says one thing: "Don't trust the police."
· Room 406 (Horror) — The phone of the last tenant, who died a month ago. Every night at 11:11, a text arrives from the dead.
· The Second Phone (Affair · Drama) — A strange phone hidden under the spare tire in your husband's trunk. On the lock screen: a woman you've never seen.
· Secondhand (Thriller · Pursuit) — The used phone you bought was never wiped. Then the previous owner starts texting: "Please, give that phone back."
· 60 Minutes (Thriller · Kidnapping) — A text arrives on a phone you found in the street: "We have the child."
· Storm Island (Mystery · Closed circle) — A guesthouse cut off by a typhoon. One guest is dead, and his phone is in your hands. The killer is still in the group chat.
· Hide and Seek (Japanese horror) — A phone found at an unstaffed station in rural Japan. The same message keeps arriving from someone named あおい: もういいかい — ready or not?
· Preview (Thriller) — 1:52 a.m. A passenger left a phone on the back seat of your taxi. It won't unlock. All you can see are notifications cut off mid-sentence.
New cases are added regularly.

■ What makes it different
· Every case plays the phone differently: one never unlocks, so you solve it from notification previews; one is entirely in Japanese and you read it through its translate tool; in another, the killer is still in the group chat.
· A phone that feels real — lock screen, notifications, home screen, even Control Center.
· Time keeps moving — texts and calls arrive on the in-game clock.
· Reply as the owner — they think you're the phone's owner. One wrong word and you're caught.
· Real deduction — puzzles you only solve by connecting a date in a photo, a line in a note, an entry in the call log.
· Twists and multiple endings — one true ending and bad endings you can retry.
· Fully voiced calls and voicemails.
· Hints when you're stuck, and "Reveal answer" when you're really stuck.

The stories take place in Korea (and Japan), fully translated into English with English voices.
Put on your earphones, turn off the lights, and begin.
What you're holding now is someone else's phone.
