New in 2.0: By default, JamBook now keeps the screen on while in a jam or while viewing a song. You can disable this by turning off the "Keep Screen On" feature in settings. Also, when you start a jam, you'll notice that the jam codes are now 6 letter words rather than a random mix of letters and numbers so they are easy to pronounce and remember.

Two new features for Start a Jam and Join a Jam: Pause the jam - Step out for a minute without giving up the code. The bar turns grey and the room plays on without you — nothing you open reaches them, nothing they open moves your iPad. Rejoin puts you back on whatever they're playing now, so you never have to remember the code. Song - Tap Song on the jam bar to open what the room is on, at the page they're on. It asks the jam directly rather than trusting what your iPad was last told, so it also rescues an iPad that missed a song — if the room has moved on and you haven't, tap Song.

Set lists - an ordered list of songs Synching of history, set lists, and user tags to the cloud (optional) in case the user has multiple devices Creating and joining jams - this syncs multiple device so they see the same song and even the same page of a song
