Why buy each?

Fitbit Charge

ECG and EDA stress in a slim band

Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.

Google apps integration

Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.

7-day battery with GPS

7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.

Apple Watch SE

Full watchOS at a lower price

Access the entire watchOS app ecosystem, Apple Pay, Siri, and Family Setup — for $150 less than the Series 11.

Crash and fall detection

Emergency SOS, fall detection, and Crash Detection give real safety value even without premium health sensors.

Aluminium in four colours

Available in Midnight, Starlight, Silver, and (PRODUCT)RED with a wide range of Apple Watch-compatible bands.
