Source verdict

The reviewer concludes that the Google Fitbit Air is a "game changer" for many people, especially average fitness enthusiasts. He believes it offers reliable and sufficient data without the recurring subscription cost of Whoop, making it a more convenient and sensible choice for the masses. He even considers switching to it himself.

About this source

The reviewer unboxes and provides a first look at the Google Fitbit Air, comparing it to the Whoop fitness tracker. He discusses its design, features, pricing model, and overall user experience, aiming to determine if it can truly be a "Whoop killer".

Review notes

The Fitbit Air is a strong contender to replace WHOOP for most users, offering essential health tracking without the burden of a recurring subscription fee. It is significantly smaller and more compact than the WHOOP, weighing just 5.3 grams, and tracks a comprehensive range of metrics including heart rate, sleep stages, and blood oxygen. However, unlike WHOOP, the device must be removed from the wrist and placed into a charging puck, which might be less convenient for continuous wear. If you are a general fitness enthusiast seeking reliable data and a sleek, unobtrusive design without a constant subscription, this device is an excellent choice. If you are a professional athlete requiring second-by-second heart rate tracking and uninterrupted data collection, the WHOOP might still be more suitable.

What the reviewer liked

  • Smaller and more compact than WHOOP
  • No mandatory subscription for basic health tracking
  • Tracks essential health data (steps, calories, distance, readiness, sleep, heart rate, HRV, breathing rate, SpO2)
  • Long battery life (up to 7 days)
  • Lightweight at just 5.3 grams
  • 50 meters water resistance
  • Affordable initial purchase price compared to WHOOP's recurring cost
  • Offers advanced features and AI coaching with an optional, cheaper subscription or Google AI Pro plan

What the reviewer criticised

  • Needs to be removed from the wrist for charging
  • Measures heart rate every 2 seconds, not every second like WHOOP
