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!)

Needs work

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.

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!!
