OGInsta+

If you’re an Instagram user, you will know that you can’t download photos and videos, at least not on mobile devices. In fact, most companies behind social networks, like Facebook or Google, don’t allow this kind of functionality, and that includes not letting them in the official store.
 
As for OGInsta+, users will find that this application is pretty much the same as the official one, but with a small difference. Users will be able to download photos and videos from the feeds. This can be a problem because the Instagram agreement that you sigh when using their service altogether forbids this action, so you will have to use it at your risk.
