Awesome!

The app is awesome! The design completely matches the OS X DNA. It goes best with the dark mode, but looks great on the normal mode too. Also, the back/forward gestures are very helpful (my feeling says that triggering it can be even better).
The activity tab works well. This is basically the reason I downloaded the app. Please keep it there...

Great job! Finally an Instagram client worth paying for.
As a feature request, a peek/pop feature in grid-view for Force touch trackpads might be a good idea.

UPDATE: I have edited my review. I mentioned some problems in my previous reivew which seemed to be existing only on my machine.
