TRX PTT
TRX PTT

Your phone is the walkie‑talkie.
The world is the range.

Press, talk, release — the way a radio works. No numbers to dial, no calls to accept, no group to set up first. Pick a channel and everyone on it hears you: the next street, the next country, the other side of the planet. Anywhere there is internet, there is range.

What it does

Everything you expect from a radio, and the few things a phone can do better.

🎙️

Push to talk

Hold the button and talk; let go and listen. Prefer not to hold it? Switch to toggle mode and one tap starts, another stops. The volume-down key and the hardware PTT button on rugged phones work too.

📻

Up to 120 channels

Step through them with the up and down keys, or tap the seven-segment display and type a number straight in. One person talks at a time, exactly like a real radio.

🔍

Scan for activity

Sweeps ten channels a second and stops where someone is talking. While scanning you are invisible: the app looks at each channel without joining it.

🔒

Encryption key

Only people with the same key hear each other; everyone else on that channel cannot hear you and cannot interrupt you. The key never leaves your phone — up to twelve characters on Pro, up to thirty-two on Ultra and on a recognised radio.

📶

Built for a bad signal

Speech is compressed to roughly 12 kbit/s — about 95 kB per minute of talking. If the connection stumbles, the app drops to a lower bitrate by itself so the conversation keeps going instead of breaking up.

🔊

Speaker, earpiece or Bluetooth

One button cycles the output. Loud on the speaker for a pocket radio, quiet on the earpiece when you hold it to your ear, or over a paired headset with its own microphone.

🌍

A flag beside your name

Two letters over the wire become a flag next to your nickname. Pick your own country, or fly something else entirely — the pirate flag is right there in the list.

🔋

Keeps listening

Runs in the background with the screen off, so a call still reaches you. A single notification tells you it is on, and the on/off switch really does switch it off.

🚫

No account, no ads

No sign-up, no email address, no password to forget. No advertising, no analytics and no trackers — there is nothing in here that follows you around.

Nothing to hide: this is our own dashboard

Most apps tell you what they collect. This is the actual page we look at, live, right now. We use it for one thing: keeping the server healthy and correctly sized.

How your data is handled

Your voice is not recorded. It is relayed to the others on your channel and dropped. There is no recording, no storage and no playback anywhere in the server — not as a feature, not as a setting, not as a hidden switch. Nothing is written to disk.

Your details live only while you are connected. Nickname, channel and country exist in memory; close the app and they are gone within seconds.

One file is written: a daily count of connections, kept for thirty days. A tally, not a record of people — no names, no channels, nothing pointing back to you.

Your IP address is used once to look up a country in a database on the server itself, and then let go. It is not stored, not logged and not shown anywhere.

With a key, listening in is out of the question. The audio is locked on your phone and unlocked on theirs, and the server moves bytes it cannot read. Without a key it travels in the open, so treat a plain channel like any radio channel — the privacy policy spells out exactly where that line runs.

Try it on a channel near you

Free, no account, and the Pro upgrade is there when you need more channels or a key.
