OGInsta +
OGInstagram is an unofficial Insta client that lets you access your account, publish photos, follow other Insta users, and do pretty much everything you can do on the official app. The main difference is that it also lets you download photos and videos from Instagram.
The entire OGInstagram plus interface is identical to Instagram's in every way except instead of reading 'Insta' along the top part of the interface it says 'OGInsta'. Everything else – profiles, photo feed, search tools, etc. – is exactly the same.
The main (and pretty much only) novelty on OGInsta plus compared to the official app is that when you press the share button you'll get an option not just to share the image or video link, but also to download it. This download takes place in the background and it goes directly to your downloads folder.
