It's good when it works... – InstaCleaner - Mass Delete & Unfollow Instagram Review

After your first 50 pictures you have to pay $4.99 for the app which I'm not sure why because it freezes all the time, you have a 50 post limit when deleting, and you have to wait like 3-4 minutes each time you want to delete. It's kind of annoying but was the cheapest on the market thus far.
