Now the best subsonic client for iOS

I was an iSub user for many years. When version 1.8 of Play:Sub came out, I found myself splitting my time between the two apps. Version 1.9 (July 2018) has changed all that: Play:Sub is the only client for me now. Why? The power of the interface. It’s very flexible for things like adding tracks to a currently playing queue. Basically, unlike iSub (which is no longer in active development) the interface feels current and doesn’t get in your way. Add in features unique to this client like Artist Radio (plays songs from artists related to the current one) and you’ve got a winner.

Awesome App! The Best Subsonic Player!

I’ve tried all of the Subsonic players and while each has it’s own style and special features, this is my personal favorite! It’s a beautifully polished app with a great interface! When the iPhone first came out the music player on iOS was wonderful. Then they mucked it up a little and completely borked it when they added streaming music. This app however still has that beautiful feel and ease of use.
I also give the developer huge props! He’s very fast to respond to support questions and welcomes feedback and suggestions.

Please give us cast options and CarPlay

I would pay extra to be able to use “cast” to capable Wi-Fi devices...this functionality is in the Google Chrome version of the web interface in the play bar, a lot of apps do this now and it would be awesome to have. I would also like to request that we get a true car play interface. This app is phenomenal please keep up the excellent work in developing!

Developer Response ,

Support for Google Cast is coming in the next version (soon).
As for CarPlay: it's on the list of candidate things to add to play:Sub, and CarPlay is getting requested more and more.
