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.

COROS Apex

65h GPS, 24-day battery (46mm)

The 46mm Apex 4 delivers 65 hours of GPS tracking and 24 days typical use — enough for multi-day mountain events without charging. The 42mm offers 41h GPS and 15 days.

Full offline maps and depth gauge

Global topographic maps with instant rendering, turn-by-turn navigation, POIs, and an underwater depth gauge — the Apex 4 is the first COROS mid-tier with a depth sensor.

Speaker, microphone, and voice notes

Audio alerts, hands-free calling, and voice pin recording — a first for the Apex line, adding practical trail and daily-wear convenience to this mountain sports watch.
