​CD Signal: Walkie Talkie

Secure P2P Audio. Works on Wi-Fi, Hotspot & 5G. Encrypted Device-to-Device Calls

Talk Instantly, Connect Securely.

CD Signal transforms your smartphone into a reliable, encrypted Walkie Talkie. Forget about typing long messages, missed calls, or waiting for a connection—just hold the blue button and speak. It works perfectly for coordinating with friends at events, hiking in remote areas, or managing teams on the go.

How it Works: CD Signal uses a secure directory server to help you find your friends, but your voice data never touches our servers. Once connected, your audio travels directly from phone to phone (P2P) and is encrypted using a unique Frequency PIN that only you control.

Why You'll Love CD Signal:

🎙️ Instant Push-to-Talk Real-time voice chat that feels just like a professional radio. Hold to speak, release to listen. No lag, no waiting.

🔐 Carrier-Grade Encryption Your privacy is our priority. Calls are automatically encrypted using your personal Profile PIN. If you set your PIN to "1234", only friends who know that code can talk to you. No strangers can interrupt.

⚡ Zero-Touch Connectivity New! No more pressing "Connect" buttons. The app automatically detects your friends via our smart directory and handles the connection in the background. Just open the app and start talking.

📡 Works Offline & Online
Internet Mode: Talk to anyone in the world over Wi-Fi or 4G/5G.
Offline Mode: No internet? No problem. Connect devices directly via Mobile Hotspot or local Wi-Fi to talk when hiking, camping, or during internet outages.

🔊 Crystal Clear Audio Optimized for modern networks, CD Signal delivers HD voice quality on 5G, 4G LTE, and Wi-Fi. We’ve eliminated audio distortion to ensure your voice sounds natural, even on mobile data.

📟 Voice Pager Mode Never miss a message. If your phone is in Silent Mode, CD Signal automatically records incoming transmissions so you can play them back later.

🤝 Connect in Seconds No complicated account setup. Just scan your friend's QR Code to pair instantly, or simply type their Frequency PIN to start a secure line.

🔋 All-Day Battery Built for efficiency. The app stays active in the background to receive calls without draining your battery, keeping you connected even when your screen is locked.

1. Login to create your secure session.
2. Pair by scanning a friend's QR Code or entering their IP.
3. Talk! Go to the Radio tab and hold the blue button.

Note: This app uses peer-to-peer (P2P) technology for audio. Audio quality depends on your network stability.
