The merging controls could be a little smoother. It's a matter of dragging two photo collections onto each other with a pinching gesture, but it took me several tries to get it to work properly. Editing Moments is a far more intuitive affair, with easy controls to dismiss or highlight photos if you don't like how MyRoll pieced together your images.
Photo sharing was a central part of the original Flayvr app, and that continues in MyRoll. The company has no interest in creating its own social network; rather it's opted to loop MyRoll into the existing services you likely already use. The app promises easy access for sharing via WhatsApp, Facebook, SMS, Twitter, and email. In fact, Facebook users can even create an album using their MyRoll Moments to share on the social networking service.
I've long since disabled my Facebook account so I couldn't test that particular feature. I did, however, share some Moments over email. The person you share with gets a link to an HTML5 album created by MyRoll (complete with a map that shows the location of where you took the photos if they were shot in one area). Users can scroll through the photos and download them individually; in a future update, MyRoll plans add the ability to download all the photos in a Moment with a single click.
