Works with no signal
Audio, photographs and the map live on your phone. Inside the excavations there is no coverage, and that is exactly where the guide has to work.
Forty-four hectares of ruins with almost no signage and no usable mobile signal. Tessera shows where you are on the plan of the park and tells you what you are looking at — downloaded before you go, working in airplane mode.
These five stories are free forever, in the app and here. No sign-up, no email — press play.

Nothing ever starts playing on its own. Walk up to something, and the app offers the story of the object next to you.
English, Russian, Spanish and German are all included. Switching language later is a download, not another purchase.
Streets, insulae, the city wall and the gates, drawn from survey data. Search finds a place by name, by number or by keyword.
Times are counted, not guessed: walking distance over the real street graph, plus every story, plus ninety seconds of standing and looking at each stop.
What people come here for: the Forum, the House of the Faun, the Lupanar, the Great Theatre. Take this one if time is short.
Frescoes, mosaics and what came out of the ground in the last few years: the Black Room, the hall of Dionysian mysteries, the bakery-prison. Guidebooks do not have these yet.
From the Marina Gate to the Amphitheatre by way of the Forum, the residential quarters and Via dell'Abbondanza. Half a day, and nothing left out.
Yes. Once downloaded, everything — audio, photographs, the map and the routes — is on the phone. You need a connection once, to download, and never again.
The app is free to install and includes five stories. Opening all 73 is a single payment of $6.99. There is no subscription and nothing expires.
English, Russian, Spanish and German — all four in the same purchase. You choose inside the app and can switch at any time.
Between one hour and three and a half, depending on the route. The shortest covers the Forum, the House of the Faun and the theatres; the longest crosses the whole city from the Sea Gate to the Amphitheatre.
Yes. Tessera is a guide, not an entrance ticket. Buy admission to the archaeological park as usual.
