Dex: Audio Tours & City Guides
Explore London, NYC, Paris
Only for iPhone
Free
Cinematic audio tours across the world's most-visited cities. Now live in New York, London, Rome, Paris, Florence, and more.
Dex turns the world's greatest places into cinematic experiences — with spellbinding stories, captivating characters, immersive sound design, and an AI guide that knows every corner.
PICK YOUR STORYTELLER
The same place, told differently. With Dex, you choose who tells the story. A historian. A rebel. A queen. Each storyteller brings a unique perspective, turning a single landmark into a battleground, a love story, or a legend.
CINEMATIC AUDIO TOURS
This is not a standard audio guide. Dex delivers full-production audio experiences with rich narration, original soundtracks, and edge-of-your-seat sound effects. Every chapter is crafted to make you feel like you are inside the story — not just listening to it.
EXPLORE ON YOUR TERMS
Stories are organized into bite-sized chapters so you can explore at your own pace. Pause, skip ahead, or go deep — Dex adapts to how you want to experience a place.
ASK DEX ANYTHING
See something interesting? Ask Dex. Scan an object, point at a painting, or just ask a question — and get thoughtful, contextual answers powered by AI. Dex is more than just a tour; it is a knowledgeable companion that travels with you.
INTERACTIVE CHARACTERS
Dex goes beyond audio. Meet interactive characters who engage you, surprise you, and pull you deeper into every location. Unlock hidden stories that make exploring fun for everyone — solo travelers, couples, and families alike.

more A lot of the mounted dinosaur bone on display is cast rather than original, with the actual fossils kept in storage. Dex explains why that is standard museum practice and not a deception, and it does so without talking down to you. The hall reads completely differently after that.

architecture major here. theres a whole segment on how the beam of light from the oculus crawls across the floor during the day and roughly where it landed on certain dates. my professors slides dont get anywhere close to that. somebody actually did the work on this

im a history teacher so i figured this would be pretty thin. but the hypogeum section, the tunnel level underneath where the animals and the fighters waited to get winched up through the trapdoors, dex actually does that right. i stood in a hot corridor for like 20 minutes just listening to it. my own students tune out when i cover the exact same material, so. humbling. security line was 40 minutes though, bring water

New: Neighbourhood Tours
Until now, Dex has lived at landmarks. But cities aren't really experienced only at landmarks. They're lived in the walks between them: the alley that smells like bread at 7am, the square where the chess players gather, the corner where the city changes character entirely.
So we taught Dex to walk with you.
With GPS triggers, neighbourhood tours are now fully supported. Wander into Trastevere or Camden Town or Harlem and Dex picks up on where you are, automatically. Turn a corner, hear a story. Cross a piazza, meet its ghosts. No tapping, no "what am I looking at" — just a guide who knows the neighbourhood as well as a local friend, narrating in real time as you walk.
Also in this release
* Zippier starts. The wait between opening Dex and hitting play just got a whole lot shorter.
* More soundscapes. Gentle ambient music on the character screen, so things hum along nicely between stories.
* Smarter downloads. Better queueing and fewer stalls when saving tours for offline use. Offline wanderers, rejoice!
* Bug squashing. A handful of small fixes to make Dex feel that bit snappier all around
