Transistor is an app for listening to radio stations over the internet.
About this app
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.

Launch the app from your home screen

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.y20k.transistor is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 4.3.6 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Transistor - Simple Radio App first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Transistor - Simple Radio App, and a listing is removed when the evidence for it stops holding up.
