Got CarPlay? AVSub supports cached music.

AVSub supports caching so you can listen to your music or watch video even when you're not connected to the Internet. AVSub will intelligently cache what you listen to in the background, or you can choose to download tracks, albums or videos direct to the cache for quick pre-loading. Cache size is configurable, along with options such as cache reading & writing and the ability to control direct-downloading over a mobile/cellular network.

Cache management in AVSub is easy too! When browsing the cache, simple swipe right-to-left on item to reveal a delete button. See the AVSub website for details.

AVSub supports Subsonic playlists and will intelligently cache tracks on your device.

AVSub can be used on both WiFi or a mobile/cellular connection (3G/4G). Audio caching ensure smoother playback.

AVSub shows enhanced information for your media, recognising movies, TV, artists and giving bio information, top tracks and similar artists.

AVSub supports the casting app AVCast.

With AVSub you can access your full media library by browsing, selecting from the most recently added, most recently played, most frequently played or highest rated tracks, or search over your entire library. AVSub also supports multiple SubSonic top-level music folders, allowing you to select an individual top-level folder, or your entire collection. You can browse by folder structure or ID3 tags.

What's New

Version 22.0

V22 of AVSub has added support for CarPlay.

If you have a CarPlay enabled car head unit, you can now launch AVSub directly to browse and play from the cache. Either play cached albums, or the entire cache. Shuffle and repeat modes are fully supported.

AVSub now integrates better with the audio from other apps. If you have voice navigation enabled and are listening to an audio book or podcast, AVSub will pause while the system delivers audio instructions. You can also force AVSub into this mode for the current track through a new speech bubble icon on the controls at the bottom of the now-playing screen.

This release also fixes a couple of bugs.

Ratings and Reviews



Noticing that many of the reviews here are very old.

Now I've used this app from its inception and while it wasn't perfect in the beginning it is so much better now. Music steams flawlessly over 3G and 4G connections, caching offline works well so you don't eat data when out and about. The interface is brilliantly designed for menu access when driving (shhh naughty).

Top notch app. Note I rarely use video functionality so can't comment on that but as a portably music player taking my collection with me works brilliantly.

Oh and on a side note it's regularly updated with bug fixes and feature requests (oh and dev actually responds to and actions feature requests if they make sense too!)

Best money I've ever spent on an app (and the longest I've ever used one I've bought too!)

Took the plunge..


Kinda got sick of isub not working under iOS 8 properly. Was really surprised with this as most subsonic clients hardly work. This one works straight outta the box with a nice fluid straightforward interface. Finally I can listen to my music again - has caching as well. Recommended!!

Needs work

A loyal chiver

Stops playing audio and complains about not being able to contact the subsonic server if it's connection fails. This is even though I have cached all the songs it's playing. App then requires me close and reopen before it will resume playing.

As an app that was originally designed to be as simple as possible for in-car use, I find it quite dangerous to be closing/reopening the app while driving.
