iOS/Android: Flayvr organises your photos and videos into moving-picture albums on your device that can then be easily shared with friends via the web. The app is actually slightly reminiscent of HTC Share in that you get a collage of pictures and videos, and the images animate to make your albums feel more active and alive.
Flavyr differs from Gallery replacement apps like QuickPic in that it doesn't pull up every photo you've ever taken, but instead attempts to curate them into related collections. You can also share a Flayvr album by uploading it to the web and sending your friends a simple simple link, similar to Vine or Instagram (minus the social network aspect).
