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.

Garmin CIRQA

Garmin metrics, no screen, no subscription

Body Battery, sleep coach, training readiness and VO2 max — the metrics Garmin watch owners rely on — in a screen-free band with no mandatory membership.

Wrist or upper-arm wear

Swap between a wrist band and an upper-arm band, which many users find more comfortable during sleep and more accurate during workouts.

Up to 10-day battery

Up to 10 days between charges, longer than the Fitbit Air's 7 days. A full charge takes up to 90 minutes on Garmin's proprietary charger.
