You love your music. In fact, you have the biggest collection of albums and individual songs of anyone you know and you listen to your playlists as often and for as long as you possibly can. Now, thanks to iSub Music Streamer, you’re enjoying your favorite songs everywhere you go, even at work or on a long plane ride.

iSub is an incredible app that lets you stream all of that music—even your concert recordings, DJ mixes, and audio books—from your home computer directly to your iPhone, iPod touch, or iPad over WiFi and mobile data.

iSub streams your music from any Subsonic compatible server (Subsonic, Airsonic, Madsonic, and others). There’s no central service to rely on and it's all your own music, so you never have to worry about songs randomly going missing when their licensing runs out like on some streaming services.

It doesn’t matter the size or file format of your collection; iSub can handle it all thanks to native support for popular lossless and lossy file formats like MP3, AAC, FLAC, ALAC, OGG, and OPUS. Save your limited mobile data when on the go thanks to Subsonic’s ability to transcode your songs to a lower bitrate as they play, and listen to your high-resolution lossless FLAC files when at home or on a WiFi connection.

iSub isn’t just about listening, either. You can easily search, browse, and edit your playlists right from you device, shuffle songs and albums, view your latest additions and far more! The current and next song caches automatically as you play, saving you money on your data plan. You can even cache whole albums over WiFi without having to play them, so you can be ready for that long plane ride.

Customize your music experience and make it just the way you want it. Don’t just get force fed music like some other apps. With iSub, you're in control of your music!

Check out the amazing features you get when you download iSub Music Streamer:

- Native support for MP3, AAC, FLAC, ALAC, OGG, and OPUS files! - Gapless playback! - Full parametric equalizer! - Works over WiFi and cellular data - Streams directly from your home computer to your device, no service to rely on - Universal app: buy once and use on iPhone, iPod touch, and iPad - Skip within tracks while they stream even when transcoding - Can lower bitrate to save bandwidth when on the go - Search your collection for albums, artists and songs from the Home tab - Shuffle your whole collection with the press of a button - Easily find your newest album additions - Caches current and next songs to your device as you play for the best performance - Cache songs when on WiFi without having to play them - Create custom playlists from your device and save them back to your server - Save bookmarks to go back to your favorite spot in a long recording or album - Supports AirPlay and Bluetooth speakers to listen with friends

My go-to Subsonic app
     
by DwayneTanner · February 29, 2024

I’ve been using ISub since about 2015. The only issue I’ve ever had with it is the lack of a decent CarPlay integration. You’re stuck using the Now Playing feature which doesn’t allow you to navigate outside the currently loaded playlist. Add that integration and it’ll be pretty close to perfect.

Tremendous Update
     
by QuintonQL · February 21, 2021

The recent work put into the app is very much appreciated. There were some hiccups for the app over the last several years, but it is once again the premier Subsonic on iOS. It has no peer on Android.

Pause between songs is annoying
     
by Danny43455 · June 19, 2021

I used iSub for a while and I like that it connects easily with my server and shows lyrics when available which is cool. But even with pre-loading of next song enabled, there is always a 1-2 second gap between songs, which I find really annoying. I reluctantly paid the $5 for the “play:Sub” app which does not have this problem and even lets you add cross fade. iSub is a good app to try out streaming from your subsonic-compatible server. But for the long-run you think the gap might annoy you, play:Sub seems to be the best iOS app.

Like a Phoenix rising from the ashes

I can’t believe this. I barely have the words but let me try and make clear, this is once again THE ABSOLUTE, NO DOUBT ABOUT IT, BEST STREAMER APP IN THE APP STORE for those of us who continue and will never stop rocking our own Subsonic, AirSonic, Navidrome collections. Wow! I had all but given up on finding even a basic app that hadn’t been seemingly abandoned and I have always loved iSub but as time marched on, it had difficulty keeping up but all of that apparently is to my great delight, in the past. Why haven't you downloaded the app and fired up your server already? Seriously you should already be doing it. This is so amazingly exciting!! I just want to give a sincere thank you to the developer who breathed new life into their app and into what I assume will be a very grateful and enthusiastic community in the days ahead. Thank you! Thank you!

Fresh and new, old and sublime
     
by Demuretwilight · December 30, 2020

I’ve been using this app for about 6 years, and new updates December 2020 have freshened it up once again. It’s always been the beat at what it does, easy use of subsonic (or other apps that use the subsonic protocols) on your iPhone. Now it functions in line with the latest iOS specs and still feels great to use. Thanks for the great updates!

Still the best
     
by ColetteLondon · December 23, 2020

With the recent update, it’s back to its full glory - easily the best way to listen to music on the iPhone.

Navidrome
     
by CengizV · March 21, 2023

Trying to connect to a navidrome server as they claim isub can handle it. I am getting invalid semicolon separator in query. So it is a solid 1 star for me.
