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 Smart Band 10

Brighter AMOLED at under $40

The Smart Band 10's 1.72" display peaks at 1500 nits — 200 nits brighter than the Band 9 — making it more readable in sunlight, all for around $40.

21-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 3 weeks before charging. Seven more days than the already impressive Band 9.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends. Bluetooth 5.4 for improved connection stability.
