I did switch to the FFmpeg streaming engine and sound quality is noticeably better.  Streams also start much faster when using this engine.  I plan to use the FFmpeg streaming engine from now on.  Thank you for the suggestion!

It's been a long time since the original post above, but I did want to point out that the current version of XiiaLive did address my concern regarding sorting of favorites.  Thank you very much for incorporating the sorting options into the app.

This is definitely good news.  I've been a XiiaLive user for years.  Even after trying and even switching to competitors I always find myself coming back.  Releasing a version of XiiaLive of the same quality as the android version over to iOS would be a huge benefit to that base of users.  There are fewer viable streaming options on that OS than there are on android.  Even the design of Shoutcast's own iOS app pales in comparison to XiiaLive.  I also expect an iOS version would be a huge benefit to XiiaLive's overall success as well considering the large base of users for the OS.

Lastly, I could see myself possibly switching to iOS in the future and this app is essential for me on both phones and tablets.  I would be missing it greatly if it weren't available to me to use.  If development of the iOS version is successful, I would suggest to make sure there is a way to restore favorites and tags from the backup file created by the android version.  Good luck with the new project developers!
