We've known about Instagram's plans to add offline capabilities to its app for a couple of months, and yesterday the news was made official at the Facebook Developer Conference (F8). Instagram is testing offline mode in regions with limited bandwidth to make the app more approachable and adapted to the demands of users there. According to the company, 80% of its community is outside of the US and many of these users are on lesser optimized networks, so making sure the app works when there's slow or no connectivity became a crucial feature to implement.

The way this works is when you're offline, you can still view the preloaded content and several of the app's sections (feed, explore, personal profile, previously visited profiles, etc) and you can interact with them.
