Why buy each?

Fitbit Sense

Continuous EDA stress tracking

The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.

6 months Fitbit Premium included

Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.

6-day battery, works with iPhone

Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.

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.
