Why buy each?

WHOOP 5.0

WHOOP Age — healthspan tracking

WHOOP 5.0 gives you a biological age score derived from your sleep, recovery, and training habits — showing whether your lifestyle is ageing you faster or slower than your years. Updated daily, it makes long-term health trends visible at a glance.

AI Coach — coaching, not just data

WHOOP's AI Coach learns your body's patterns and delivers personalised daily recommendations in plain language — not just what happened, but why, and what to do next. It adapts to your training load, sleep debt, and recovery trends.

Strength Trainer — weight room coverage

WHOOP 5.0 added a dedicated strength trainer that auto-detects sets, measures neuromuscular load alongside cardiovascular strain, and shows recovery demand from resistance training — a gap every previous WHOOP version had.

Fitbit Versa

Works with Android and iPhone

Rare for a smartwatch with real GPS and health sensors to work fully on both platforms — Versa 4 does.

Google Maps and Google Wallet on wrist

Turn-by-turn navigation and NFC payments without needing your phone in hand.

6-day battery and Fitbit health coaching

Sleep stages, daily readiness score, Active Zone Minutes, and SpO2 — all on a 6-day charge.

Pick the WHOOP 5.0 if…

Athletes, coaches, and fitness-obsessed users who want deep recovery and sleep data without screen distractions. WHOOP suits those who train hard and want to understand whether their body is ready to push. Not for casual users or those who want smartwatch features like notifications or GPS.
