Undertone: Talk Through Noise

You're shouting from eighteen inches away and your friend still can't hear you. Put an earbud in, share a 4-digit code, and suddenly you're talking at a whisper while the venue rages around you. Undertone gives a group of friends a clear voice conversation in places where talking is impossible: loud bars, concerts, clubs, airplane cabins, ski lifts, separate cars on a road trip — and now, with push to talk, for groups of up to 16. HOW IT WORKS 1. One person taps HOST and shows a QR code. 2. Everyone else scans it, or types the 4-digit code. 3. Talk normally. Hear everyone clearly. That's the whole thing. No sign-up, no internet, nothing to configure. WHY IT'S DIFFERENT • No internet, no accounts. Your phones connect directly to each other over local wireless. It works in a basement bar, on a plane, in the middle of nowhere. • Two ways to talk. Live rooms for 2 to 8 people in continuous conversation, or Push to talk for up to 16 — one speaker at a time, and it works farther apart. • In with 4 digits. Joining takes seconds with a code or a QR scan. • Android friends can join. With Undertone for Android, iPhone and Android can share a room when everyone is on the same Wi-Fi network or a phone hotspot. • Engineered for loud venues. Noise suppression, per-person volume, and a low-latency mode keep voices clear when nothing else is. • Friend radar. See where your friends are around you, live on screen (iPhone to iPhone, iPhone 11 and later). • Private by architecture. There are no servers. Nothing is recorded, nothing is uploaded, and when the night ends the room is gone. Join by QR code and your voice is encrypted between phones. MIX YOUR OWN TABLE Tap a friend's circle to make them louder or quieter, just for you. Mute someone just for yourself. They'll never know. Muted but want to jump in? Hold the mic button to talk, release to go quiet again. In a Push to talk room there's no mute at all: hold Talk to speak, let go to listen, and see who's talking and who's next. WORKS WITH WHAT'S IN YOUR EARS AirPods shine here, but any Bluetooth earbuds work, along with wired headsets and MFi hearing aids. GOOD TO KNOW • Live rooms: 2 to 8 people, best close together. Push to talk rooms: up to 16 people, and they work farther apart. • iPhone (iOS 17 or later) or Android (Undertone for Android, Android 8 or later). Everyone needs Undertone installed; Push to talk needs version 2.0 on every phone. • iPhone-only rooms connect phone to phone with nothing to set up. Rooms that mix iPhone and Android need everyone on the same Wi-Fi network or a phone hotspot. • If the host leaves, the room passes to the next person and the conversation keeps going. • The host's phone mixes the audio, so pick the one with the most battery. Bring it somewhere loud.
