Why buy each?

Fitbit Edge

Larger AMOLED display with always-on option

A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.

Built-in GPS, ECG, and an altimeter

Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.

User-replaceable battery

Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.

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.

Bottom Line

Technical gaps
  1. HR sampling. 5.0 polls at 26 Hz vs 0.5 Hz — 52× more frequent. Matters for HRV precision and high-intensity HR accuracy.
  2. 5.0-only sensors: Respiratory Rate, Strain Score, Blood Pressure, VO2 Max.
  3. Weight. Edge is 9g lighter — relevant for all-day comfort and sleep.
  4. Water resistance. 5.0 rates 10ATM vs 50m on Edge.
Commercial gaps
  1. Hardware cost. 5.0 is $179 cheaper upfront ($0 vs $179).
  2. Subscription. WHOOP 5.0 requires a subscription ($199/yr) — device stops working without it. Fitbit Edge has an optional subscription.
  3. 3-year total cost. Edge costs $476 vs $597 — a $121 gap.
Pick the Fitbit Edge if…

Anyone who wants a slim tracker with a screen, built-in GPS, and ECG rather than a full smartwatch. It suits Charge owners ready to upgrade, as long as they don't rely on Google Wallet payments or EDA stress scans. Works with both Android and iPhone via the Google Health app.

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.
