Fitbit Air: Sixth Wearable Watershed

The Fitbit Air is here, making waves as the sixth significant wearable since 2012. Beyond its affordable $99 price tag, it's the advanced health metrics and accurate heart rate tracking that set it apart. With a battery life of up to seven days, it outlasts the Apple Watch (two days) and matches the Coros Apex Pro (seven days). Its lightweight design at 18g is lighter than the Garmin Venu 2 (50g), making it perfect for all-day wear.

The Air's star feature is its ECG app, offering on-demand readings and irregular heart rhythm notifications. It also tracks sleep stages and provides a detailed breakdown in the Fitbit app. While it lacks built-in GPS like the Garmin Forerunner 245 (built-in), it connects to your phone's GPS for outdoor tracking.

The Air is water-resistant up to 50 meters, offering basic activity tracking without overwhelming features. It's not a direct Whoop competitor but sits comfortably between the Fitbit Charge 5 and Versa 3 in terms of features and price.

Verdict: Not perfect, but solid. The Fitbit Air offers advanced health metrics at an affordable price with impressive battery life. If you're after a no-frills wearable focused on health tracking, this is your runner-up to the Apple Watch.
