Fitbit Air
Buy/Wait:good

First-generation product — no historical cycle data to predict a successor

Best for: Health-focused users who want passive, 24/7 biometric tracking without a screen on their wrist. Particularly strong for those drawn to WHOOP but put off by the subscription model — the Fitbit Air delivers comparable core health data for $99 outright. Works with both iOS and Android.

Why buy each?

Fitbit Air

$99 with no subscription

Unlike WHOOP, there is no mandatory membership — pay $99 once and use Fitbit Air with the free Google Health app. Google Health Premium ($9.99/month) is optional.

24/7 health monitoring in 12 grams

Continuous heart rate, SpO2, HRV, and skin temperature tracking plus background FDA-certified AFib detection, in a 12g pebble designed to be worn and forgotten.

7-day battery with 5-minute fast charge

A week between charges, with a 5-minute top-up delivering a full day of use — significantly less downtime than WHOOP's slide-on charging system.

Suunto Vertical

AMOLED display — first for the Vertical line

The Vertical 2 replaces the MIP screen with a bright 1.5" AMOLED LTPO — delivering vivid colour maps and improved night readability while still providing 65 hours of dual-band GPS.

Built-in LED flashlight

An integrated LED flashlight is new to the Vertical 2, adding practical trail and camp utility without a separate device — especially useful for early morning and night runs.

Full offline maps, 65h GPS, AI Coach

Global topographic maps with dual-band GPS, 20-day smartwatch battery, and an AI Coach that personalises training load and recovery recommendations directly on the watch.
