This app delivers on what it advertises. I use it with Audiobus and apps such as iMaschine and Audioshare to record loops. There are audible glitches at times, but they dont show up in my recordings. The latency at a even slightly higher setting is workable in that I can play an instrument on one device and not get tripped up by the delay. Remote control of record stop/start from the opposite device is a nice touch. Worth the $ in that I can now consolidate hardware I was using to stream audio between devices.
