Anybody else remember an end-user-agreement or opting in? I don't recall any end-user-agreement language or any opt-in choice popping up when I installed the VSCO app on my iOS devices (it was a while ago), nor do I recall either on entering the app after updates. So, like most of tech these days, it's a contraction of tool capability in the name of "convenience" and bigger, business-to-business corporate great question! Off hand, I don't know the answer. Of course, for the user, it remains "a process" to get images from a "real" camera on to (or off of) an iPad or an iPhone and VSCO's app doesn't come close to offering Lightroom's flexibility. They're running the Adobe play, here: more or less, you'll get the same "look" by processing on mobile, but VSCO gets $20 a year from your wallet and, more importantly, they get your images in their cloud to train the subject-recognition / data-harvesting AI they market to other big businesses.
What I'm talking about is the VSCO mobile app & cloud, which offers all the film presets (and many more, for an in-app fee), and uses iOS's built-in RAW compatibility to work with RAW files you've pulled in from your "real" camera (or shot straight from your phone's cam).
Just an FYI, Bob: VSCO did make a wrapper-host.
