Creating posts for later posting in Instagram is a drag. Right now the options are pretty limited. You can use an app like Grum (which violates Instagram’s Terms Of Service, not a good idea). Or maybe, you can create yourself a reminder to post something and post it manually later. None of those options is very enticing.
Photographer Eric Pare shared a quick and (extremely) dirty tip on how to prepare Instagram posts and publish them later. It is still a bit manual and definitely not elegant, but it works.
The secret is to “post” to Instagram without any active internet connection. Instagram will try posting then (obviously) fail, and will wait for you to re-initiate the post.
So edit the photo, put your tags and description, and right before you hit the publish key start flight mode (you can quickly access it via the android notification screen or iOS’s setting screen)
Now you can turn flight mode on. The photo will not be posted until you manually hit the resubmit button
