Frequently asked questions

No. Visitors install no app and create no account: they go to tt24.es with the room code or scan the QR.

An iPhone with iOS 15 or later, or an Android phone with Chrome 105 or later, plus earphones.

Audio is sent compressed, on iPhone too, so it uses little data, which matters when visitors are roaming.

Yes. Audio keeps playing with the screen locked.

Yes, on the Original channel: the guide's voice as it is, for those who speak the guide's language.

Yes. They can send messages, which the guide reads translated, and talk face to face, each in their own language.

If the guide turns it on, a PDF summary of the tour in their language.

Spanish, today.

Yes. We have our own glossary of more than 4,000 terms, curated in each language: monuments and cities, architecture and art, Spanish cuisine, idioms and proverbs, kings and historical figures, and IT terms.

It has been tested with 60 listeners in one room, and more visitors cost no more.

Yes. Tested on tours of more than an hour and 45 minutes non-stop, in several languages at once, and it worked properly.

The guide sees the group on a map and gets an alert if someone wanders off; they can also set a meeting point.

On tour operators' coaches, a 4G travel router with its own wifi. In places without a network, custom audio guides, downloaded on joining the room and played offline. And if the connection drops, visitors rejoin their room on their own.

If the guide's phone loses signal for a few seconds, their voice is stored (up to 30 seconds) and translated as soon as the connection is back: the translation is not lost.

The audio guide for your own tour, with your voice and your words. You record or write each stop, it is translated and voiced automatically, and visitors listen offline by tapping the number you show them. They are included. How they work.

There is a guide app for Android, with which the microphone keeps working with the screen off or while using WhatsApp. Without the app, the page locks the screen with a black layer so it keeps picking up sound.

The guide gets a “They can't hear you” alert and it reactivates on its own.

A room with a code that never changes, per coach or per route. The guide shows it on their phone, as a code or a QR.

Tour audio is not recorded. Visitors do not create an account or give personal data to listen. The text of what the guide says is used for the PDF summary, which is deleted after 6 hours, and stays in the server's technical logs, which are deleted automatically after a month. Data is hosted in Europe.

For guides, no fees and no commitment: you only pay in the months you use it, and what counts is the time the microphone is on, not how many visitors listen. Work out your month with the price calculator. For tour operators, pricing is fully tailored: write to us and we will arrange a meeting, in person or online, where you will see your quote there and then.

Yes. Sign-up is free: fifteen minutes to try it, with 10 languages at once and no card details. The minutes only count while the microphone is on and cannot be extended; when they run out, write to us and we will set up your account. The guide panel is in Spanish for now. Sign up for free. If you would like to see it first, we do a 15-minute demo with just a phone.

No. Independent servers in Europe, not shared hosting: a complete infrastructure, with security and monitoring, run by our own team.
