Audio Hijack Pro and Fission are two of the best, simplest, and most useful apps I've ever used, bar none.…These two apps have made me seem like a genius to my digitally-challenged musician friend. Some of the guys he plays with aren't going to be around all that much longer, and your software is helping me preserve their incredible playing -- plus my friend's, who's an awesome but underappreciated talent.…You guys rock…Better value for software I've never seen.
Personal recommendation: Go buy @RogueAmoeba new version of Fission. It's even better than v1.
