Don't be afraid to talk back

Vi talks to you like an actual person, not a robot, to encourage you during a workout. When she senses your heart rate is too high for fat burning during a run, she'll tell you to slow down. Or she'll count off the miles during a long cycling trip, cheering you past your distance goal. Best of all, you can talk back and ask Vi to log or adjust workouts, switch modes, or even fire up your Apple Music or Spotify tunes. Vi will schedule in your daily or weekly workouts, shoot you a text if your outdoor plans are about to get rained out, and help you take control of your fitness goals!
