This source's evidence 🎬

Source verdict

The reviewer did not provide a definitive verdict as this was a preview, not a full review, but expressed surprise at the Fitbit Air's capabilities without a subscription. He noted the device's comfort for sleep tracking and indicated particular interest in how its automatic activity detection performs in practice.

About this source

This review provides a preview of the new Fitbit Air screenless health and activity tracker, detailing its design, core tracking capabilities, and integration with the new Google Health app. It covers the device's $99 price point, optional premium subscription, and comparisons to competitors like Whoop and Pixel Watch. The reviewer highlights features such as automatic workout sensing, enhanced sleep accuracy, and flexible multi-device integration within the app.

Review notes

This new Fitbit Air offers an intriguing screenless tracking experience at an accessible price point, positioning itself as a strong competitor to devices like Whoop. Its comfort and ability to work alongside other devices like the Pixel Watch for combined data are significant advantages. However, it lacks advanced features like ECG and GPS, which would rely on a connected phone, unlike more expensive smartwatches. If you prioritize a comfortable, discreet, and affordable health tracker for continuous monitoring and sleep, this is a compelling option. If you require on-device GPS, ECG, or automatic rep counting for strength training, you should explore other options.

What the reviewer liked

  • Screenless, lightweight, and minimalist design for comfort
  • Affordable at $99 with optional subscription
  • Tracks heart rate, calories, blood oxygen, HRV, skin temperature, training load
  • Automatic workout sensing that learns patterns over time
  • Comfortable for sleep, includes smart wake alarm
  • Long battery life (about a week) with quick charge feature
  • Google Health app compatible with Android and iPhone, can merge data from other devices
  • Can work alongside a Pixel Watch for comprehensive tracking

What the reviewer criticised

  • No armband option at launch
  • Lacks ECG, GPS, and barometric altimeter (unlike Pixel Watch)
  • No automatic rep counting for strength training
  • Accuracy expected to be slightly less than Pixel Watch due to smaller sensor
  • Premium subscription required for advanced AI insights and coaching features
