How it works

📡

Station sources

Point the app at any JSON file on the internet (or a local file / folder on your device) and your stations load instantly. Change the JSON and the app picks it up on next launch — no app update needed.

🔗

Deep links

Share a multiradio://load?url=… link. Tapping it on any iPhone with the app installed loads your station list instantly — no copy-pasting into Settings.

CarPlay

🚗

Full CarPlay support

Browse your station list and start playback right from your car's dashboard. The now-playing screen is pushed automatically when a station starts, showing artwork, title, and artist from the live stream metadata.

Support & FAQ

How do I add a custom station list?

Host a stations.json file at any public URL and open Settings → Station Sources in the app, then paste the URL. Or use the deep link below to load it with a single tap from a webpage or message.

Load this site's default station list

multiradio://load?url=https%3A%2F%2Fradioapp.jtw.dk%2Fstations.json

Open in Multi Radio App

What is the multiradio:// deep link?

The app registers the multiradio:// URL scheme. A link in the form multiradio://load?url=<percent-encoded JSON URL> tells the app to fetch and use that JSON file as its station source. Build one in PHP:

<?php
$jsonUrl  = 'https://your-server.com/stations.json';
$deepLink = 'multiradio://load?url=' . rawurlencode($jsonUrl);
?>
<a href="<?= htmlspecialchars($deepLink) ?>">Open in Multi Radio App</a>

What audio formats and stream types are supported?

Live streams: MP3, AAC, HLS (.m3u8) over HTTP or HTTPS, including plain-HTTP streams (ATS is open for live radio). ICY/Shoutcast metadata (song title + artist) is read from the stream headers.

Local files: MP3, AAC, M4A, M4B, FLAC, WAV, OGG, Opus.
