Mark up to 32 talkgroups and contacts and the radio listens to all of them at the same time.
- Nothing missed while it looks elsewhere
- Holds a call long enough to answer it
- Any bound key stops it, on Open DMR Terminal
Connect over the internet, key up, and talk to operators anywhere in the world - in your own language. No extra hardware. No ads. No tracking. Completely free.
Everything a licensed operator needs to get on the air over the internet.
Mark up to 32 talkgroups and contacts and the radio listens to all of them at the same time.
The stations around you on a real map, one tap from a message.
A driving screen with buttons you can hit without looking. Tap anywhere to talk.
Homebrew repeater links and Open DMR Terminal hotspots alike - and the app always tells you which one a session is speaking.
Any DMR master server. Hold or tap, or bind a hardware or Bluetooth key that keeps working with the screen off.
Talkgroup calls and 1-to-1 private calls, a single tap apart.
Who is talking, as it happens - callsign, country flag, target and duration. Choose the columns you want.
Pick a server and the list narrows to that DMR network, colour-coded wherever it appears.
Talkgroup and DMR-ID directories with search, favourites and recents, refreshed daily.
On-device AMBE via the MD-380 vocoder, automatic gain on RX and TX, manual gain when you want it.
A call takes the speaker: the radio mutes and drops your transmission, then comes straight back.
Your grid locator to the network on connect, and optional beaconing with SmartBeaconing. Both off by default.
Several identities, networks and talkgroups - swapped in a tap.
Profiles, talkgroups, contacts, servers, favourites and settings to a file - and back again on a new phone.
The whole interface in 26 languages, switched instantly - no restart.
Type "busy", "gain" or "vibrate" at the top of Settings and land on it, whichever section it lives in.
A clean, modern interface in light and dark. Swipe through the app.
Z3DMR running on a real phone - a walk through the screens, menus and options.
Screenshots only get you so far. This is Z3DMR on an ordinary Android phone - moving through the tabs, opening the pickers and settings, and showing how the app behaves as you use it.
No hotspot. No dongle. No radio. Just the phone in your hand.
Enter your callsign and DMR ID, then pick a master server from the searchable directory - BrandMeister, TGIF, DMR+ IPSC2 or any Homebrew-protocol network you have access to.
Search the built-in directory, star your favourites, or dial a private contact by callsign or DMR ID.
Hold to talk, release to listen. The activity log shows who's on frequency, live. That's it - 73!
The habits of a real radio, kept - grouped by what you are actually trying to do.
No ads. No analytics. No tracking.
Your profiles never leave your phone. Master-server passwords are encrypted with the Android Keystore.
No advertising, no analytics, no crash-reporting SDKs. The app talks only to the DMR network you choose - plus the public APRS-IS network if you switch on beaconing, messaging or the map, and OpenStreetMap for the map's own tiles.
As with all amateur radio, transmissions aren't encrypted and are heard by others on the talkgroup. That's how ham radio works.
Microphone only while you hold PTT - audio is never recorded or stored. Location is never asked for at startup: only the feature that uses it asks, when you switch it on - grid locator, APRS or the map. Bluetooth is asked for by Car Mode's Bluetooth trigger, which reads only devices you have already paired and never scans, and by the Bluetooth push-to-talk button picker, which is the one screen that looks for nearby devices - and only while it is open. The optional accessibility service is used for one thing: noticing the hardware keys you bound. It never reads your screen.

A tool for licensed amateur-radio operators. You'll need a valid licence, a DMR ID and access to a DMR network.
