Simple, but effective
Updates have fixed most of the serious flaws adressed in earlier reviews. It’s simple premise is it allows uploads to instagram from your Mac, and it does that effectively, even allowing you to adjust the crop to square, or by adjusting to keep the original dimensions (like SquareReady). Also allows you to to add captions on intial upload. You can add a few basic photo effects, but don’t expect much here. It’s not made for browsing and commenting, just for uploading. Given this, it’s a little pricey.
