Love this, but one feature suggestion

I use this with my booksonic server connected to unraid and it works beautifully. However, there’s 1 feature I would love to see you implement (btw, I’ve downloaded every subsonic music/audiobook player and none have it) is being able to play back at faster speeds. I have some audiobooks which are great, but the narrator speaks at terribly slow pace. Hopefully you can implement this feature relatively easily and soon! Otherwise, love the app and features!

-update: and this was improved! We have faster playback, integration into every Bluetooth/wireless device I have. I’ve deleted all my other apps and use this one exclusively. Works with my audiobooks, podcasts and on a separate server I’ve linked my music. Overall, this is a total win!

Variable playback speed will be part of the next version.

Awesome app- fast and easy to use

I’ve tried a number of free apps for my playing music off my airsonic server and this is by far the best. It’s extremely fast loading as if the songs were on the device instead of streaming. I can’t even tell it’s streaming, honestly. It’s easy to queue songs, albums, genres, years, artists, etc on the fly. It shows my artwork properly also. I’ve only used it for a few days, but well worth the purchase price.

You can also set max nitrates (for Wi-Fi and cellular) to help limit data usage, customize cache sizes and download music directly for offline play. I haven’t yet found a feature I want that is missing, and I am someone that likes a lot of settings/tinkering and features! Keep up the great work, dev.

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.
