What is an audio guide app? A short guide for travellers

An audio guide app is software, usually on a phone, that plays narrated information about a place — a museum, a neighbourhood, a single landmark — while you stand in front of it or walk through it. It replaces the rented headset at a museum, the printed guidebook, and (for some travellers) the human tour guide.

That is the literal definition. In practice the category covers four very different products. This guide explains the differences and helps you pick the right one for the trip you're on.

The four types of audio guide app

1. Museum audio guides

The simplest type. A specific museum publishes its official audio guide as an app. You download it, walk into the museum, type a number on your screen at each artefact, and listen. The Louvre, the Uffizi, the British Museum, and most major institutions now offer one.

These are usually free, made by the museum itself, and only useful inside that museum. Often distributed through aggregator platforms like izi.travel.

2. Fixed-route walking tour apps

A producer designs a walking route through a city neighbourhood — the Roman Forum, Montmartre, Soho — writes a script, hires a voice actor, and packages it as a single tour. You buy or download the tour, follow the route, and listen. Apps like Rick Steves Audio Europe, VoiceMap, GPSmyCity, and izi.travel sit here.

The strength: high editorial quality, professional voice, focused experience. The weakness: you're locked into a specific route and a specific city. If you wander, the app loses its place.

3. POI database apps

Apps that list every Point of Interest in a city — restaurants, museums, monuments — and let you tap each one for information. Google Maps and TripAdvisor are the obvious examples. They're not really audio guides; the information is text-first, audio is rare.

The strength: comprehensive. The weakness: information density, no narrative, no story.

4. Ambient discovery apps

The newest category, and the one Naruho sits in (disclosure: I built Naruho). These apps don't pre-package tours. They pick up the landmarks within a small radius of where you stand, in real time, and serve you stories about whichever ones you tap. On the better implementations, audio plays hands-free as you walk.

The strength: you set the route. Coverage is typically global rather than city-pack-based. The weakness: less editorial curation than a fixed-route product, and depth depends on the underlying map data.

Which type should you use?

• Inside a museum: the museum's own audio guide. Use izi.travel or the museum's app.
• First time in a city, fixed itinerary: Rick Steves Audio Europe (free, covers most major European cities) or VoiceMap (paid, more global coverage). Both are fixed-route.
• Looking up a specific place: Wikipedia or Google Maps. They are not audio guides, but they are exhaustive.
• Wandering, repeat visitor, off the obvious route: ambient discovery. Try Naruho. The pattern fits this case better than any fixed-route app.

What a good audio guide app does

• Plays in the background while you walk, hands-free, so you keep looking at the world rather than your screen.
• Has stories, not Wikipedia walls. Three to five sentences, one surprising angle, a story arc.
• Works offline once a place is loaded, so a poor signal doesn't break the experience.
• Doesn't spam you with recommendations. Pulls when asked. Stays quiet otherwise.
• Personalises to what you actually care about, instead of giving you the same "top 10" everyone else gets.

What a bad one does

• Reads paragraphs of encyclopaedia text aloud.
• Makes you download a city pack before it works.
• Locks you into a route. If you deviate, the app stops.
• Pushes notifications about places you didn't ask about.
• Hallucinates landmarks that don't exist.

How to pick

For most travellers, the answer is two apps in your pocket: a fixed-route app for the planned highlights of a city you've never visited, and an ambient discovery app for everything else.

Naruho is built for the second case. Read how it works, or see which cities have rich coverage.
