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.

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.

WhatsNew:

- updated software libraries
- modernised the build setup

Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos. For details on this, please see here.
