SubStreamer is a completely free app to use with any subsonic compatible music server (subsonic, airsonic, madsonic, navidrome, ampache etc). Your music when you want it, where you want it, online or offline.

Easily see newly added, recently played and most played albums or just grab a list of random albums or songs for something different.

Like that song? Play similar songs with a tap!

Discover new songs and old favorites by genre and time period with SubStreamer radio. Pick your filters and get a random generated playlist, just like radio without the ads!

Got a song stuck in your head? Sure that you have it on an album somewhere but just can't remember where? Just search!

Connect your subsonic server with your account and Substreamer can also tap into to give you more information about artists, songs and albums in your collection and recommend similar artists, similar songs or give you a list of the top rated songs in your own collection for you to explore.

Build up a play queue of your favorite rock songs and just hit save as playlist to have it stored on the server for later.

Of course you can also just hit your favorite album and press play.

Oh and if Music isn't enough we also support podcasts that you have synced with your subsonic server both online and offline!

It works but it doesn't

When trying to stream anything that isn't in the "new" section it crashes with SIGABRT, all albums are listed as "()" with no picture, and I have to start tracks twice, once to transcode and another to play the transcode result. I can send the crash logs if anyone wants them.

Fix plz! Review will go from a 1 star to almost a 5 with these fixed

The Substreamer app is a WONDERFUL app and it provides a fantastic service but some bugs make it impossibly frustrating to use!

1. This isn’t too huge of a problem because it’s not that bad I’ll still point it out this app takes entirely too long to load especially if after a few minutes or I open too many other apps or sometimes if I get a phone call the app will kick forcing me to reload the app a search for whatever it was. This can occur several times within my short 17 min commute to and from work.

2. I am not totally sure if the bug that’s at hand but when a content provider uploads say, an album when you access that album you’ll see double postings of each song. It’s only when you enable view offline that this problem is fixed.

3. Whatever is the root cause of the previous issue brings forth another bug. Sometimes when browsing the album I’ll select at track and the track just will not play, the app will know the song is selected and the monitor in my vehicle will even display the song. Occasionally if I choose the duplicate track the song will start but in far many instances I’m still with silence.

Best Free Subsonic App

Edit: Out of all the apps that I saw that had updates, this was the last one I was expecting, especially since the last update was three years ago. The update fixed nearly all of the issues that I had with the prior version, and added a few other new neat things. Thank you for taking the time to revive this app! Updated to to 5 stars.

Original Review:
Compared to some of the other free options out there, this one is the best. However, it is in dire need of an update. Sometimes, I cannot scroll up and down through my library, the only way to fix is by restarting. I would like to see better control from the lock screen (eg: being able to scroll through the song). Also, a dark mode would be nice.

That being said, I would happily pay for this app in its current form.

It was indeed in dire need of an update, now an update is here! Please give it a try!
