Psychopedia maps 970 documented true-crime cases across 25 US cities, each one pinned to the address where it actually happened. Read them anywhere, listen while you walk, or let the app tap you on the shoulder when you are close.
Nothing is gated behind being somewhere. Browse the whole atlas from the couch, or take it out the door.
Pick a city, or start where you are. Every pin is a documented case at its real address, colored by kind, from the 1690s to today.
Each case is a written dossier: what happened, when, exactly where, with archival photographs and the list of sources it was built from. On narrated cases, press play and a documentary voice reads it to you, in English or Spanish.
Turn on proximity alerts and Psychopedia tells you when you walk near a documented scene. You choose the radius, the kinds of cases, quiet hours and a daily limit. The matching happens on your phone; your location never leaves it.
Every case on this map happened exactly there.
West Village, New York. 138 documented cases inside the city limits, pinned to the door.
A tour strings real scenes into one route and tells each story where it happened. Put your headphones on: the narration starts on its own when you reach each stop, and the app shows the way to the next one.
Reading stays free: the full file behind every stop is in the atlas.

A tour costs between US$9.99 and US$14.99, paid once. In the app, the Tours tab filters the same way: by city, by theme, on foot or by car, and the ones you own.
No points, no streaks, no autoplay. The cases, where they happened, with their sources.
Six kinds of cases, each with its own color and glyph so they stay apart even if you are color-blind. Slide through eras, filter by city, zoom from the whole country to one block. The pins are the catalog: every droplet is a real case at its recorded coordinates.
Proximity alerts, entirely on your terms.
Dates, an address with a confidence level (exact, block, or area), archival photography with its license, and every source listed by name. Read the list yourself.
A documentary voice reads the case to you, in English or in Spanish. About half the catalog, more than 490 cases, is narrated in each language so far, and the rest are on the way. Put your headphones on and walk the block while it reads.

The Cocaine Cowboys, the mob’s winter capital, the serial killers: collections chosen and ranked by an editor, not assembled by an algorithm.

Cases are pinned to where they happened: a corner, a lobby, a bar, the street you live on.
Three cities carry the deepest catalogs. The rest are the places a single famous case pulls people across the country to see.
Each one opens into a written account, its sources, and the exact spot on the map. Every case reaches you with a picture: an archival photograph where one exists, a map of the exact coordinates where it does not.
