What if your phone started collecting photos you never took? What if a second camera app appeared on your device that nobody installed? What if someone read your messages before you sent them? Kaidan is a short-form J-Horror reading app that reimagines Japan's centuries-old ghost-story tradition for the smartphone generation. Each story can be read in about one minute and ends on an unresolved detail that lingers long after the final line. 【Flagship Series: Everyday Doors】 Tagged — your phone collects photos of you in places you have never been. Camera 2 — a second camera app appears that nobody installed. The Other Mother — the school remembers your second child, but you only have one. The 13th Floor — your building doesn't have one. Seen — someone reads your messages before you send them. 【Five Categories】 • Digital Horror — social media, notifications, and the internet after dark • Everyday Disturbances — reality shifting one degree at a time • Urban Legends — stories the city refuses to forget • Unsolved Mysteries — unanswered questions and missing pieces • Japanese Kaidan — the tradition itself 【The Reading Experience】 • Read in about one minute • Original J-Horror stories • Classic Mode for uninterrupted reading • Cinema Mode for immersive vertical storytelling • Switch modes instantly with a single tap 【The Truth Ritual】 Every story ends with a question. The truth waits behind a single rewarded video. The first few Truths are available without unlocking. 【Daily Drip】 A growing library of original horror stories. New stories arrive regularly, with fresh tales appearing throughout the launch period and beyond. 【10 Hand-Curated Languages】 English, Japanese, Korean, Simplified Chinese, Traditional Chinese, Spanish, French, Portuguese, Vietnamese, and Thai. Every translation is adapted to feel natural within its own language and horror culture. Free to read. No subscriptions. No in-app purchases. Just one minute, one story, and one lingering fear.
