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 Venu

ECG and Garmin Body Battery

The Venu 4 adds on-demand ECG (a first for the Venu line) alongside Garmin's signature Body Battery energy score — combining health monitoring and daily readiness in one watch.

Built-in flashlight and speaker

A white/red LED flashlight and a speaker/microphone for hands-free calling — practical features that set the Venu 4 apart from the Venu 3.

Multi-band GPS, 12-day battery

SatIQ multi-band GPS for precise tracking in cities and trails, with up to 12 days of battery life in the 45mm model — significantly more than any comparable smartwatch.
