App for Instagram Videos/Stories download I am interested in creating a mobile app for downloading videos/photos/stories from Instagram. The idea is simple: the users provide links of the instagram posts they wish to download and they directly save them to their phone's photo library.

Would this somehow violate Instagram's terms of service or Apple's? Would the application be taken down from Apple's app store?
You would need to get permission from Instagram for it not to be removed, you might also have copyright issues.
