The easy way to test your broadcasts, whether you are just getting started streaming your gameplay on iPhone and iPad or you are a game developer testing your game. For ReplayKit live broadcasts.

• FOR MOBILE STREAMERS: Want to check your camera lighting and voice levels before going live? Take a few previews with DevStream first, and play them back to get an idea. Then try broadcasting from your chosen game to DevStream too.

• FOR GAME DEVELOPERS: Developing a new game or adding ReplayKit live broadcasting functionality to an existing game, but don't want to send your tests to the masses? Start with DevStream. In fact, we made this app precisely because we didn't have a way to test our own game's ReplayKit functionality before going live.

• SAVE YOUR CLIPS: DevStream will save a sequence of MP4 video clips to your Photo Library; each broadcast gets a new album. You can change the duration of the clips and also choose to discard the broadcast altogether if you want a '/dev/null'-like sink for your broadcasts.

NOTE: ReplayKit live broadcasts are still a new feature, and can sometimes be buggy and/or include artifacts like stuttering, hitching, etc. The real broadcast solution you choose might have different broadcast characteristics (for example: movie clips vs. samples, compression options, Internet connection quality, etc.) than DevStream, so your end result on a different broadcasting app is not guaranteed to look or sound like your DevStream broadcast. Not all devices support broadcasting.
