Insta Archive helps you create galleries from Instagram photos. You can view your Instagram feed and save the good photos to look at them later. Your photos will also be grouped in categories so no need to organize them.
Your Instagram feed is shown on home page and the ones you swipe right will be saved in to your personal private gallery. The ones you swipe left will be gone from this world never to be seen again.
You can also toggle Showing/Hiding button to hide the people you dont want to see. Dont worry they wont know you unfollowed them ;)
Your Followers and the people you follow wont be able to see when you save photos. You also wont be able to give likes to the photos, so we can say you are completely anonymous.
