iSub lets you stream your personal music collection from your home computer directly to your iPhone or iPad, regardless of size and format. Even FLAC!

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!

The best is back

I’m pretty sure this is the most weirdly emotional I’ve ever felt about an app update.

I gave iSub 5 stars and a review back in 2012, and from that point til the Great Disappointment of 2020 it was an almost infrastructural part of my life. I deliberately held off on updating to iOS14 for so long that I eventually forgot that it was a strategic position I was holding, just to keep this app alive. The moment when, late at night in the throes of the pandemic and perhaps in my cups, I absentmindedly tapped “Update” then instantly realized the sonic ramifications of my actions, was one of shock and trauma and genuine human grief.

My months in the wilderness were hard, Reader. So hard. As the American Experiment seemingly crumbled around me, I tried every other Subsonic app in the App Store. None could compare. I began listening to the Bandcamp app almost exclusively, the rest of my collection fading into memory.

And so today, when I found this update, It was like Dorothy opening her eyes for the first time in the technicolor of Oz. Like, “Yes. This. THIS. This is the 2021 I was promised.”

I’ve been sitting around listening to tunes all evening, marveling that iSub is not only back, it’s better. Ben did it. He BUILT BACK BETTER. The design is clearer, the way it navigates my truly massive library is lightning quick, the new bells and whistles are all intuitive and cool. The best is back. Thank you, Ben. You really, really made my day.

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!

Wow, thank you for the iOS v14 update

ISub stopped working after upgrading to iOS 14 on my iPhone, I was very disappointed and was about to write a command. Then, I see the app had an update 17 hours ago (after years of no updates). Problem solved!!!

One request: please don’t show the auto cached songs because it clutters up my real downloads, which makes my downloads hard to navigate. Or, have a separate tab for user downloads, as opposed to auto cached songs.

Great app, have been using it for years.
