How do I respond to messages with my Fitbit device?

Use quick replies to send customized responses to text messages and messages from certain apps with Fitbit Charge 3, Fitbit Charge 4, Fitbit Ionic, or Fitbit Versa series. This feature is currently available on devices paired to an Android phone. Devices paired to an iPhone or Windows 10 phone can only respond to Fitbit app notifications, such as messages, cheers, taunts, and friend requests.
