And this app definitely predates a filtered global. Just tapped on Global in Zephyr and o.O
Of course you might wonder why I care about iOS 5 capability. It's because I've been messing with a third gen iPod Touch which only runs iOS 5.1.1.
I guess this app doesn't have PMs. Which might be a problem since I use PMs a lot.
@matigo it does but you have to take the photos outside of the Instagram app and hit the little button. It will share a square (with letterboxing) and non-square version of the photo.
I was shocked I had an ADN app that still runs on iOS 5, but here it is: Zephyr.
