Vimeo was widely considered to be the king of the mountain when it came to video quality, user interface, and community. I count myself among the folks who used Vimeo for the first two or those three selling points but am now preparing all of my media for an exodus over to YouTube.
My first thought when Apple released this today was "Please be compatible with the Rode smartLav(+)" and, to my delight, it is. I'm a big fan of the smartLav for both weddings and quick interviews, but not so much for the accompanying iOS app which is horribly outdated and very buggy for me.
The Music Memos app doesn't seem to offer any kind of volume adjustment, which makes me a little nervous but my initial tests with it, using wildly varying vocal volumes, didn't show any clipping whatsoever. It might just be the perfect companion app for the smartLav. I'm going to continue testing and see if it's a viable option for use in the field.
There's a lot of talk about the impending release of iOS 9, most of which revolves around the content blocking feature that's built-in for developers to program against. I have a feeling the top-grossing apps this Fall will almost assuredly be content blockers and I'm personally pretty excited about that due to the very sad state of mobile advertising.
