What are Sparks?
Sparks are a one-time use token that can be sent to another member who has sparked your interest. Send one by tapping the Spark button that appears between the Pass and Like buttons while viewing a profile. The member you Spark will receive a notification and will see Sparks raining down on your profile when they view you!
If another member has sent you Sparks, you'll receive a notification when you log in, keep swiping through new profiles to reveal who has sparked you!
