StorySave

If you’re using Instagram, you know that you can’t really save something for later. If anything, it’s going to be lost in a sea of posts and other content, never to be seen again. The StorySave wants to repair this problem by allowing users to save the story.
This feature sounds like something that Instagram should have by default, and not something that can be achieved through a third-party application built by a single programmer.
As you can imagine, one of the reasons why you can't’ save the stories on Instagram is that it’s not entirely legal, so the right idea is to ask your friend for permission before saving the content on your device.
