Step Gazelle sets your daily step goal from your own recent step history. Beat your 3rd-lowest day from the last 30 days, and your gazelle crosses the savanna to the watering hole. As you build your streak, your goal rises, moving you toward the target you set. How it works Your daily goal is your 3rd-lowest step count from the past 30 days. When you've been walking less, it's easier. As you build consistency, your daily goal rises. Hit your goal, and today counts toward your streak right away. Miss a day? Spend a pass to save your streak. Your gazelle A savanna scene tracks your day. Your gazelle walks toward the watering hole as you walk and reaches it when you hit your goal. Give your gazelle a name, and tap it to say hello. Trends See your step history by week, month, or six months. Track your average and distance, see how they compare with the previous period, and watch your steps rise over time.
