I recently talked about sharing Instagram videos on Vine, a multi-step procedure that involves a third-party app to save an Instagram clip to the Camera roll before posting it manually to the Twitter-owned Vine service.
So far so good.
But what about the other way round? Of course that same process applies to posting vine clips on Instagram: save a vine to the device before manually sharing it on Instagram.
As it turns out, there's a bunch of third-party apps in the App Store which can take the pain out of resharing vines on Instagram. With VineGrab, a free iPhone app by Xiaoyu Xia, not only can you watch vines in a more elegant interface than Vine's own, you can also repost your favorite ones to Instagram.
