Kinda expensive


Would be 5 stars but you have to purchase each additional feature. Feels a bit like nickel and diming.

Feeling generous


I'm delighted to see someone tackle the problem of accessing subsonic while driving. iSub is the best iOS app available for subsonic right now. But it is really quite sad that that is the case. iSub has a confusing interface when you're not also trying to drive a car. It is absolutely maddening to use while on the road. So points for addressing this problem. Improvements are needed however. Most importantly: playlist support. Recently added and listened to is nice, but nowhere near as useful as access to the many subsonic playlists I've already created. Ability to star tracks would also be nice (iSub doesn't offer that). Also, why double tap on artwork for play/pause (had to visit web site to figure that one out)? I see no downside in using single tap for that instead. Easier while driving and more discoverable. Also, landscape view option is essential for an app that purports to be car-friendly (iSub supports landscape). Since most gps apps work best in landscape mode, that's how my car mount is oriented. I experienced performance issues as well: I was frequently unable to navigate as expected as though the app had frozen or something. But overall, this app holds great promise. If development continues and my concerns addressed, the stars stay.

Great app, BEST subsonic App available

AVSub is the ultimate pairing with the Subsonic media streaming platform. It works exactly as you would expect it to in terms of functionality, and has a lot of convenient and user friendly features, ESPECIALLY the support for Chromecast and high-res output to a DAC... making this app essentially perfect for any mobile audiophile set up.

What sets this above above and beyond the rest is not only the feature set, but the developer himself. I had a few technical problems with the app when I first started using it, however after working with the App developer he was persistent with my issue and followed through with updating the app to fix ALL of my problems and kept me up to date through the process. You don't get that kind of support from other indie devs out there.

Thanks Richard for the great app and customer service. I highly recommend this app.
