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 2 to 8 people a clear group voice conversation in places where talking is impossible: loud bars, concerts, clubs, airplane cabins, ski lifts, separate cars on a road trip. 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. • In with 4 digits. Joining takes seconds with a code or a QR scan. • 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 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. 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. 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 • 2 to 8 people per room, everyone within about 30 feet. • Everyone needs an iPhone (iOS 17 or later) with Undertone installed. • 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. ## Key features - Direct peer-to-peer connection - No internet required - 4-digit code or QR join - Per-person volume control - Noise suppression - Friend radar (iPhone 11+) ## Frequently asked questions about Undertone ### How does Undertone work in loud places?
