You can find detailed information about how to earn a Super User badge here.
For Android Users:
But if you would like to check your personal progress towards earning a badge, visit your badge page on your profile. You can get to this page by clicking on the badge icon underneath your profile picture (even if you do not have any badges, you will have a gray badge icon). Click on the badge you would like to check the status of, and it will tell you how far away you are from earning it. You may need to use the app for more days, support more friends, or invite more users to display. With this feature, you can know what to focus on to move up through the ranks and earn more money. Good luck!
