A curated set of ham radio, SDR and off-grid apps for Android. Add them all in a few taps, and they keep themselves up to date.

Set up in three steps

  1. Install Obtainium

    Obtainium is a free, open-source app that installs and updates apps directly from their official sources (GitHub, F-Droid, APKPure and so on).

    Get Obtainium

    Download the app-arm64-v8a-release.apk file (it works on almost every modern phone). Open it and allow "install unknown apps" when Android asks.

  2. Download the radio app list

    A single file with all apps and their source settings.

    Download radio-apps.json
  3. Import it into Obtainium

    In Obtainium, open Settings → Import/export → Obtainium import and choose radio-apps.json from your Downloads folder.

    Then go to Apps, tap Select all, and choose Install / update. Obtainium will check for new versions and tell you when updates are ready.

Install these separately

These apps can't be added through Obtainium. Install them from the store or site below. Your Play Store or the developer handles their updates.

Or add apps one at a time

With Obtainium installed, tap Add on any app below to open it straight in Obtainium.
