Hinge's "We Met" feature is designed to "provide better recommendations in the future."
Between 4 p.m. on March 7 and midnight on March 8, you have to fill out the "We Met" form on Hinge, after reactivating your account.
First, confirm that you met.
Then, you'll answer some questions about your date, and if they're the type of person you'd like to see again, in a form consisting of their name, email, and a description of the date.
