Reaching out to Instagram users with limited network connectivity or those without data plans, the social network is bringing offline support for its Android app as announced at Facebook's F8 developer conference. They started with Android first as it’s considered the preferred type of device in the developing world. According to Tech Crunch, Instagram is exploring the possibility of bringing it to iOS, too.
In offline mode, you will be able to see previously loaded content in your feed, profiles you visited before and old versions of the Explore tab will be visible, too. You’ll be able to leave comments, like photos, unfollow people, or save media. All these actions will then be carried over once you reconnect.
