Really limited. I thought it would be an add on to my instagram app but its a whole new one in itself. You have two ways of viewing photos. You can either search hashtags (not users) or you can see your feed. Thats it. If you happen to want to regram a pic thats not in your feed and has no hashtag youre out of luck. Deleting this.
