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.

Fitbit Edge

Larger AMOLED display with always-on option

A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.

Built-in GPS, ECG, and an altimeter

Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.

User-replaceable battery

Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.
