In The Know and On The Move
Track your activity at a glance. Fully automatic tracking means no buttons to press. The tachometer-inspired sub-dial tracks progress towards your daily goal. Activité Steel automatically detects and tracks all activity, including walks, runs, swims, and sleep. Set your personal goal in the Health Mate app. Activity automatically syncs to the app via BTLE (Bluetooth Low Energy).
Water Activity Encouraged
Activité Steel is water-resistant up to 5 ATM (50 meters - 150 feet). Steel automatically detects swimming, so you can track and analyze your water workouts in the Health Mate app.
Sleep Tracking with Silent Alarm
Activité Steel automatically detects sleep, and recognizes sleep patterns including light and deep sleep cycles, sleep interruptions, and the total duration of sleep. Set a silent alarm in the app to start your day with a gentle wake-up vibration.
No Charging Needed
No need for any cables or dock - Activité Steel operates on a standard button cell watch battery to provide up to 8 months of battery life. No charging means you never miss a step.
Visualize Trends and Data
Steel syncs automatically with your phone so that you can track all progress and view graphs in the free Health Mate app. The app offers expert coaching every step of the way with Activity Insights, a Leaderboard, and Reminders to help you reach your goals.
