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.

Suunto Race

Significantly improved heart rate accuracy

The redesigned optical HR sensor on Race 2 delivers far more reliable readings during high-intensity sessions — a notable weak point of the original Race that has been addressed.

Dual-frequency GPS at 55h

Dual-frequency L1+L5 multi-constellation GPS for sub-meter precision in urban areas and dense forests, with 55 continuous GPS hours on a single charge.

1.5" AMOLED, thinner and lighter

The display grows to 1.5" at 2000 nits while the case slims to 12.5mm and drops to 76g — more readable in sunlight and easier to wear day-to-day than its predecessor.
