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.

Xiaomi Watch

6-day battery on Wear OS

Dual-chip design keeps the main Snapdragon W5 dormant during light tasks, dramatically extending battery life beyond any rival Wear OS watch.

Wear OS 6 with ECG and eSIM

First Wear OS 6 device on the market — with ECG monitoring, EMG gesture control, and eSIM for standalone calling.

1.54" AMOLED at a competitive price

A larger display than the Galaxy Watch 9 (1.47") or Pixel Watch 5 (1.4"), though not as bright as their 3,000-nit panels, with Hasselblad-tuned health sensors, starting at around $285.
