Push-to-talk walkie-talkie for your phone — with text, options, and location built in.
Tetracom is a modern, internet-based replacement for the CB radio. Hold the button, talk for a few seconds, and your voice arrives at the other side, played through their phone's speaker — no ringtone, no voicemail, no group chat back-and-forth. Just a short, fast blurt.
Use it to coordinate with your family at an amusement park, keep in touch with a group on a road trip, or check in with relatives who aren't on mainstream messengers. Tetracom blurts are end-to-end encrypted for 1:1 conversations and server-relayed for groups and offline recipients.
Three tabs. No thread view, no inbox-zero pressure. Hold the button, talk, let go. The other side hears you through their phone speaker like a walkie-talkie. v0.6.3 adds an in-app map, a Text button on the Talk tab for written questions, and a response popup for the asker.
Hold the mic button to transmit. Release to send. The other person hears it out loud.
Pick one or many. Fan out to a group with one PTT hold. Attach a file or send a location.
Fine-grained permissions. Grant your location only to the contacts you trust.
The new Text button sits next to the mic. Where am I? drops a pin on an in-app OpenStreetMap view.
Receive a question with tap-to-answer buttons. End-to-end encrypted, with optional timeout.
When your recipient taps an option, you see the original question and their answer. Tap the History entry to re-open it later.
Available in the United States. Other regions coming as they launch.
During the prototype, there is no Play Store listing yet. The Android build is distributed as an APK from the install page. Windows and iOS clients are planned.
Tetracom lets you reach users as they walk into your geogrid — a bar in the French Quarter during Mardi Gras, an airport concourse, a stadium, a festival, a mall. Your account sends an introductory voice or text blurt; the user sees your branded message only when they have opted in to receive location-based offers.
Tetracom is opt-in for location-based business messages. Users choose to receive them; they can block any business instantly. Business accounts are verified and rate-limited. Tetracom excludes under-18 users from all business targeting. US launch only; we expand jurisdictions as we verify compliance in each market.
Business-account onboarding is opening in a separate portal in the prototype phase. Fill in the form below and we'll follow up from ads@tetracom.me. Prefer email? Write to us directly.
Tetracom exposes a small HTTP + WebSocket API for registered client apps. During the prototype the base URL is plain http://; production will use HTTPS on port 443. See /api/health for server status.
