Integration
Stella + Fitbit
Fitbit tracks your daily health fundamentals: sleep, activity, stress, and heart rate. Stella uses this data to show you which of those fundamentals are showing up in your skin scores.
What Stella reads from Fitbit
Sleep
Sleep duration and stages. Stella correlates sleep quality with next-day skin hydration, clarity, and under-eye appearance.
Stress management
Fitbit's stress score reflects your body's response to daily demands. Higher stress periods often coincide with increased skin sensitivity and breakouts.
Activity
Steps, active minutes, and exercise. Stella tracks whether high-activity days influence oil production or post-exercise skin changes.
Heart rate
Resting heart rate trends provide a background signal for overall stress and recovery, both of which influence skin appearance.
How Fitbit data shows up in your skin
Fitbit captures the daily rhythms of your body. Stella captures the daily state of your skin. When you see them side by side, the connections become hard to miss.
