The Withings Activité Steel is an activity tracker that does not look like an activity tracker. Its simple and stylish design will compliment any outfit, tracking your daily activity without getting in the way. The Steel will happily track when you run, walk, swim or dance without needing your phone connected to it. Instead, it will automatically measure everything via the patented Connected Movement Technology and can be synced to your phone later with the Health Mate app for a more detailed look at your results.
