About this app

Unknown is an archive of the unexplained. Real paranormal cases, told like case files: what was reported, who reported it, what the records show and what is still argued about today.

A black cat walks beside you through the archive. Open a file, follow the witnesses, read the documents, compare the explanations and decide for yourself.

EIGHT COLLECTIONS, 120 CHAPTERS
- Ghosts & Hauntings
- UFOs & Encounters
- Cryptids
- Urban Legends
- Unexplained Mysteries
- Haunted Places
- Dark Folklore & Legends
- Strange Phenomena

READ A CASE LIKE AN INVESTIGATOR
Every case is built from the story itself: witness accounts, documents and records, timelines, key facts, competing explanations and the moment the case turns. Each source is labelled for what it is, a record that can be checked, a witness account, a tradition or a hypothesis, so you always know what kind of evidence you are reading.

THE ATLAS OF THE UNEXPLAINED
The real places behind the stories, on a world map: castles and rectories, lakes and forests, air bases and lighthouses. Filter by collection or region, open a place and read the cases that happened there. Every place you read about is marked as discovered. Coordinates come from Wikidata.

YOUR OWN STUDY
- Continue any case at the exact page where you stopped
- Save the cases you want to keep
- Close cases, earn achievements and climb the investigator ranks
- Explore by phenomenon, region, era and nature of evidence
- A certificate for every collection you finish

READING MADE FOR THE NIGHT
A dark, quiet design with a parchment reading mode and adjustable text size.

It is one purchase, yours for good: no subscription and no renewals. Already bought it? Restore it from the paywall on any device signed in to the same store account.
