Catchin' Sync is an iOS app that will work on iPhone or iPads allowing you to capture and determine any sync errors in your playback system. These usually occur when video and audio go throughout separate devices like the Audio passing through a receiver or more commonly the video through and LCD screen or worse still a Projector etc. Catchin' Sync has been around for over a year now and has been steadily improving. The latest version - 1.0.7 has really brought Catchin' Sync into the frame, because it now uses the high frame speed video recording that Apple introduces in the iPhone 5 and 5s. This has to be a 'must have' for anyone who works with video with a DAW like Pro Tools.
