This is pretty neat. I actually very much like how they split up their applications into Layout, Instagram and Hyperlapse. It keeps the main app simple and it's probably easier to update / experiment that way. I also don't mind replacing these ugly / ad-banner filled apps that exists for these little Instagram tasks with official Instagram apps.

I think it just doesn't have https for the images. Turning of httpsanywhere for tumblr fixed it for me.
