Seld

Seld turns the phones your group already carries into a tour guide audio system. You speak once; everyone hears you — with no radio rental, no shouting, and no internet connection. 🔊 LIVE VOICE TO THE WHOLE GROUP • Speak once, everyone hears it in real time • Clear, low-latency audio built for noisy places • Pause, resume and mute with one tap 📴 WORKS WITH NO INTERNET • Offline mode: your group joins a local Wi-Fi network — a phone hotspot or the venue's own Wi-Fi. Nothing leaves the building. • Online mode: share a 4-digit room code and people join from anywhere 👀 SEE WHO IS STRUGGLING, BEFORE THEY DROP • Each listener reports their connection, so a weak signal shows up while you can still do something about it • Someone who loses connection stays on your list instead of just vanishing • With their permission, see where they were last and how far away that is — for the moment somebody wanders off 💬 QUESTIONS WITHOUT INTERRUPTING • Group chat for questions, addresses, photos and map links • Two-way voice: a traveller can ask to speak with one tap • Live polls when you want the group to decide together 🌍 SEVEN LANGUAGES • English, Turkish, Spanish, French, German, Chinese, Arabic • Follows your device language, switchable in the app 📲 SET UP IN UNDER A MINUTE • Guides: one tap to start broadcasting • Travellers: scan a QR code or type the room code • No account needed to listen 👥 BUILT FOR ✓ Walking tours and city sightseeing ✓ Museums and galleries ✓ School and university field trips ✓ Bus and coach tours ✓ Factory and site visits ✓ Conferences and simultaneous interpreting ✓ Pilgrimages and large group coordination 🔒 PRIVACY • Offline sessions stay on the local network — audio never reaches a server • Location sharing is off by default and each traveller turns it on themselves • Room codes and host approval control who gets in GROUP SIZE A phone hotspot comfortably carries a small group. For larger tours, connect everyone to the venue's Wi-Fi — it still needs no internet, and it is what lets a big group listen at once. REQUIREMENTS Android 8.0 or later. Offline mode needs Wi-Fi; no mobile data required. Seld is free to use. A Pro upgrade raises the participant limit and adds host controls.
