I didn't completely understand on the first read what your app did. I read it as taking video of websites -- which is silly, but I thought I'd mention it.
Maybe "Pick your favorite sites" is unnecessary right up front? You mention later it integrates with my favorite sites and I see YouTube etc...
Same here - didn't get it at all at first. When I read "Pick your favorite sites. Take a video. Swipe to share.", I thought that it allowed you to share videos that you found on YouTube or other video sites, which didn't make any sense.
I get it now. Head a bit fried today so can't really think of a better strap-line right now though.
I used the online Stanford CS139P class and some PeepCode screencasts to get started. I come from a web dev background so it was difficult for me at first to wrap my head around Objective-C, but after using those two resources I was able to understand the syntax (and the SDK) much more clearly.
I have a similar idea but its based on candid videos where you choose your sharing site first, tag who will be in the video, hit record and once you hit stop it will automatically upload the video, right then and there. Videoroulette :D
