Poster is a software application for people who would like to have the mobile Instagram user interface on their MacOS. Generally, the desktop Instagram experience isn’t as intuitive and engaging as the one on smartphones and tablet PCs. And there hasn’t been any official announcement yet to improve on this scenario. Poster, by Mihael and Luka, is an unofficial app that brings the mobile Instagram experience on MacOS. The app achieves this by wrapping the Instagram website with Electron. By the way, the Windows version of this client should be out soon.
