# Undertone > Private group voice chat and push to talk — no internet, no accounts.

One person hosts a room, friends join with a 4-digit code or a QR scan, and everyone talks over earbuds: live conversation for up to 8, or push to talk for up to 16. No internet, no phone numbers, no accounts, no servers.

HOW IT WORKS
• Host a room and share the 4-digit code — friends nearby join in seconds
• Join by code, QR scan, or an invite link
• Phones connect directly to each other — on modern Androids there's nothing to set up: no router, no hotspot, no network at all
• On older phones, everyone joins the same Wi-Fi or a hotspot instead — the app tells you which applies
• iPhone friends can join too: Undertone for iPhone is on the App Store, and iPhone and Android can share a room when everyone is on the same Wi-Fi or a phone hotspot
• Works completely offline — in the woods, underground, or anywhere without coverage

PRIVATE BY DESIGN
• Join by QR code and your voice is encrypted between phones
• No account, no sign-up, no personal data collected, no location used
• Nothing passes through a server — your voice travels only between your phones
• Rooms vanish when the host ends them

MADE FOR REAL CONVERSATIONS
• Live conversation or push to talk — hold Talk to speak, see who's talking and who's next, and the host can take the mic
• Voice quality tiers and noise suppression tuned for noisy places
• SoundStage adds natural room ambience so voices don't sound flat
• Save frequent rooms and rejoin them with one tap
• See who's talking at a glance

BUILT FOR LONG SESSIONS
• Battery-aware networking keeps power use low
• Automatic recovery from audio interruptions, route changes, and dropped connections
• Keeps working with the screen off

Direct phone-to-phone connection uses Wi-Fi Aware, available on most recent Android phones (Android 13 and newer with supported hardware). Rooms that include an iPhone use the same Wi-Fi network or a phone hotspot. Push to talk needs Undertone 2.0 on every phone. Undertone is in beta — we'd love your feedback as we expand what it can do. ## Rankings - #2,562,129 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_LOCAL_NETWORK` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.BLUETOOTH_CONNECT` - `android.permission.BLUETOOTH_SCAN` - `android.permission.CAMERA` - `android.permission.CHANGE_NETWORK_STATE` - `android.permission.CHANGE_WIFI_MULTICAST_STATE` - `android.permission.CHANGE_WIFI_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_MICROPHONE` - `android.permission.INTERNET` - `android.permission.NEARBY_WIFI_DEVICES` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECORD_AUDIO` - `android.permission.UWB_RANGING` - `com.android.vending.CHECK_LICENSE` - `com.likelylabs.undertone.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Anonim Talk](https://chrome-stats.com/d/io.anonim.p2p) — 385 users - [Offline intercom](https://chrome-stats.com/d/com.motointercom) — 11,689 users - [Walkie Talkie (100% Offline)](https://chrome-stats.com/d/com.brightsun.walkietalkieoffline100free) — 2,982 users - [TransportChat](https://chrome-stats.com/d/dev.alsatianconsulting.transportchat) — 125 users - [CampChat — offline mesh chat](https://chrome-stats.com/d/net.rygielski.campchat) — 28 users - [offline chat](https://chrome-stats.com/d/com.happinessaitech.offlinechat) — 7 users - [Enter-Comm: Offline Intercom](https://chrome-stats.com/d/com.entercomm.bikeintercom) — 802 users - [No Trace: Private Code Chat](https://chrome-stats.com/d/com.teamzlab.no_trace_code_chat) — 571 users - [SoundBridge](https://chrome-stats.com/d/com.krishn.broadcast) — 11 users - [bono.chat](https://chrome-stats.com/d/chat.bono.app) — 54 users - [Offline Chat Voxari Messenger](https://chrome-stats.com/d/com.voxari.voxari) — 188 users - [discreed – Private Chat](https://chrome-stats.com/d/com.discreed.app) — 240 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.likelylabs.undertone)
