Why buy each?

Amazfit Band 7

18-day battery at under $50

18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.

Alexa built-in

Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.

PAI health scoring

Amazfit's Personal Activity Intelligence score aggregates your daily activity into a single 0–100 health index, guiding you toward optimal activity levels.

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.
