Transistor is a radio app with a minimalistic approach, that may not be to everyone's liking. It has no radio station discovery feature. Transistor only offers a very simple search option and it imports audio streaming links, when you tap on them in a web browser.

Transistor is free software. It is published under the MIT open-source license.

VERIFY APK

FREQUENT QUESTIONS

HOW CAN I ADD A RADIO STATION There are three ways to add a radio station to Transistor: Use Search, add playlist file address (M3U, PLS), enter a raw stream address.

WHERE DO THE RADIO STATION SEARCH RESULTS COME FROM? Transistor searches the radio-browser.info online database. You can help out the radio-browser.info community by adding the missing station (http://www.radio-browser.info/gui/#!/add) to their database.

HOW CAN I CURATE THE RADIO STATION LIST? Use the swipe gesture to delete a radio station from the list. Further editing options can be enabled in Settings. If enabled, tap and hold a radio station to edit its name, image or streaming link.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
