Snoopreport is an Instagram activity tracker that allows you to monitor the actions of users with a public profile. I use this tool to keep up with the interests of my friends and fav celebrities. It is quite handy because you get weekly reports on which hashtags and posts users like, their thematic interests, as well as new followings and unfollowings. The big advantage is that there is no app to install, this is an online tool that you can use on any device. You don't need to have your own Instagram profile to follow someone's activity. After Insta removed the ability to monitor friends' activity through the following tab, this tool is the most reliable and cheap solution. However, it is impossible to track private Instagram profiles.
Didn't track ANY activity for a full week even though I know the user was very active that week. I emailed support and they just said "as we can see the service did not track actions made by the monitored user", and won't reply to my emails any further. Don't waste your money.
I bought this so i could see if my girl was cheating or what things she liked/said on other post but was disappointed when i found out it says "we are unable to track this account right now!" her account is on public and since this is the only reason i bought it im keeping the 1 star until fixed
