If you’re a hardcore Instagrammer, when you’re on your Mac, you may want a richer experience than what the Instagram website has to offer. Fortunately, Grids for Instagram ($5) by ThinkTime Creations has you covered with a full-featured Instagram client that provides a dedicated, high-resolution window into the social network. Now in its third version, Grids provides a sleek adaptive UI with full Retina Display support, and the latest update brings that Retina quality to the images themselves with high-resolution photo support. Non-square photos and videos are also supported, and white space can be automatically trimmed from your photo view.
