RA Rosetta Audio Guides Self-guided audio tours
No signal needed

It works where your phone usually doesn't.

Museums are notoriously bad for phone signal — thick stone walls, basements, deep galleries — and that is exactly where you need your audio guide to work. So Rosetta Audio Guides is built offline-first: download a tour before you go and it plays from your phone with no internet connection at all. No data charges, no buffering, no spinning loading wheel while a queue builds behind you at the door. This page explains how it works and why it matters more than almost any other feature.

Why offline matters

The feature that decides whether a guide actually works.

An audio guide that needs the internet to play is, in a museum, a guide that often does not play at all. The very buildings that hold the great collections — old, thick-walled, frequently below ground — are the ones that swallow phone signal whole. We have all stood in a gallery watching a stream refuse to load while the moment passes. An offline-first app removes that failure entirely: once a tour is on your phone, the museum's lack of signal is simply irrelevant, because nothing needs to be fetched. The tour is already there, playing from your device, as reliable as a song saved to your music app.

This is why we treat offline not as a nice extra but as the core of the product. Every tour in the library is downloadable, the download is quick on any wi-fi, and once saved a tour stays on your phone until you remove it — so you can download on the hotel wi-fi the night before and arrive at the museum needing no signal and no data at all. It also means travellers on a foreign SIM, or with no roaming data, lose nothing: the tour works exactly the same whether you have five bars of signal or none at all, which is the whole point of building it this way.

How to use it

Download once, listen anywhere.

Using offline mode is simply a matter of downloading before you go. Three things to know.

Download on wi-fi

Save your tours the night before on the hotel or café wi-fi. They download in a minute or two and use no mobile data, so you arrive at the museum fully loaded with nothing left to fetch.

It stays on your phone

A downloaded tour remains on your device until you choose to remove it — so you can keep a tour for a return visit, or download several for a multi-museum trip and have them all ready.

No data, no roaming worry

Because the tour plays from your phone, you need no signal, no mobile data, and no roaming plan on the day. Ideal for travellers abroad who would rather not burn through data or hunt for a wi-fi signal in a foreign city.

Offline questions

What people ask about downloads.

Will a tour work without a signal?

Yes — that is the entire point. Once you have downloaded a tour, it plays with no internet connection at all, so the museum's lack of signal is irrelevant. Just remember to download before you go in, ideally on wi-fi.

How much space does a tour take?

A tour is just audio, so it is modest — comparable to an album of music, far smaller than a video. A few tours sit easily on any modern phone, and you can remove one after a visit to free the space if you wish.

Do I need data to buy a tour?

You need a connection to download a tour (wi-fi is ideal), but not to play it afterwards. So buy and download on wi-fi, then listen offline. Purchases themselves are handled by the app store, as the privacy page explains.

Download tonight, tour tomorrow — no signal required.

Get the app, save a tour on wi-fi, and the museum's dead zones stop mattering.
