Fitbit Charge 3 Fitness Activity Tracker — Advanced Health & Fitness Monitor

The Fitbit Charge 3 Fitness Activity Tracker is your everyday wellness companion, built for both men and women who want to move more, sleep smarter, and stay on top of their goals. With a 1.35-inch LED display and a lightweight silica gel band, it sits comfortably on the wrist through workouts, commutes, and everything in between.

Key health and activity insights you’ll actually use

• 24x7 heart rate tracking: Gain deeper insight into calories burned, resting heart rate trends, and overall cardiovascular health around the clock.
• Sleep monitoring: Automatically captures light sleep, deep sleep, and REM stages; view patterns to optimize recovery and daily performance.
• All-day activity metrics: Track steps, distance, and calories burned to keep you accountable without manual logging.
• Blood pressure monitoring: Measures blood pressure data as part of your wellness overview (data synced to the app for trends and context).
• Swim-ready design: Water resistant up to 50 meters, so you can swim, shower, and train without removing your tracker.
• Smart reminders: Get call, text, and app notifications right on your wrist, plus weather and calendar updates.

Smart features that fit real life

The Charge 3 pairs with your smartphone via Bluetooth 4.0 for seamless syncing and real-time pace and distance when you’re outdoors. While it doesn’t include built-in GPS, it leverages your phone’s GPS to map routes during runs or rides, giving you accurate pace and distance without carrying extra gear. The display is easy to read at a glance, so you don’t have to fumble with your device during workouts.

Durable, comfortable, and adjustable

The silicone (silica gel) band is gentle on skin and easy to swap, so you can customize the look with minimal effort. The aluminum alloy case adds durability without bulk, making it suitable for gym sessions, hiking, or daily wear. With a battery life of up to 3–5 days on a single charge, you’ll spend less time tethered to a charger; a full 0–100% recharge takes about 2 hours.

Designed for a global audience

Language support includes English, Spanish, French, German, Korean, Japanese, and Arabic, ensuring you can navigate menus and insights in your preferred language. It’s compatible with both Android and iOS devices, so most smartphones can leverage its health data and notifications.

Who is this ideal for?

Anyone seeking a stylish, feature-rich fitness tracker that covers daily activity, sleep health, and smart notifications in one affordable device. It’s particularly well-suited for runners who want smartphone-backed GPS pace, swimmers who need reliable water resistance, and anyone who values a clear, continuously updated view of their health trends.
