Rankit is like giving scores to a bunch of things that you want to compare. For example, you want to rank your favorite ice cream flavors from 1 to 5. You might give chocolate the highest score of 5, vanilla a score of 4, strawberry a score of 3, mint chocolate chip a score of 2, and rocky road a score of 1.
Rankit is useful because it helps you organize things in order of importance or preference. Maybe you want to know which ice cream flavors are the most popular in your area, or you want to know which flavor to order at the ice cream shop next time.
Rankit can be used in many other situations too, like ranking the best movies of the year or the most popular songs on the radio. Just remember, the higher the score, the better the rank.
