At present Juke only supports Apple AirPlay. We are actively working on supporting as many proprietary wireless speaker systems as possible.
You will need a Spotify Premium account to play music via Juke. If you have an ad supported free account, you can still broadcast your music tastes and listen via another user of Juke.
We use your phone's Bluetooth to broadcast and find the music tastes of nearby users.
Juke uses a relatively new Bluetooth protocol called Bluetooth Low Energy or Bluetooth 4. It's designed to use as very little battery, over a long period of time. You shouldn't notice any more battery drain than usual.
You can only change your choice of playlist inside of Juke. If you want to add/remove tracks from the playlist you have selected, you can do this in your Spotify app or Spotify web player.
We're working on adding this feature, but for now you can just delete the app and redownload.Launch the App Store on your iPhone, tap on Updates, then Purchases; you should be able to find Juke in that list to redownload.
Sorry about that, I'm sure you picked some right saucy tunes as well. We're working to improve the reliablitiy of the Bluetooth connection with each relase, but here are a few tips that should improve your experience:
There sure is, two ways; you can either put you phone on silent by flipping the switch on the side. Or you can turn on Do not disturb in control center.
Maybe one day! We don't have any Android expertise at the moment but if that changes we'll look into building an Android version of Juke.
