In present time, everyone wants a healthy life without any issues and complete sleep, which gives you peace of mind. Google has introduced a product, which is screenless fitness tracker designed for continuous, distraction-free health monitoring. Serving as an affordable alternative to Whoop, it relies on a minimalist form factor to passively gather baseline health biometrics and push deep analytics straight to the newly updated Google Health companion smartphone app. 

The company said the Google Fitbit Air — currently available for pre-order and officially ships on May 26, 2026 — tracks your sleep stages, heart rate variability, SpO2, skin temperature, resting heart rate and atrial fibrillation alerts, with a battery life of about seven days. 

It is important to note that the Fitbit Air, priced at $99, includes an updated sleep score algorithm, which is roughly 15% more accurate than the competitors. 

What does Google Fitbit Air offer?

Google has made its Fitbit Air a mere 12 grams, less than half the weight of the Whoop 5.0, which weighs in at 26.5 grams (the Whoop MG is 27.3 grams). The sensor area, which Google describes as a 'pebble', is also slimmer in height and narrower in width than Whoop.

Whenever you're using the Google Health app, you will be able to talk to your AI coach by voice or text, with the conversations powered by Google's AI chatbot Gemini. You'll need your phone to do this, but for athletes who like to talk to their AI chatbot, you'll be able to talk in real-time. You'll be able to ask questions and make requests as you workout.

Whether you're a Android or iPhone user, the Fitbit Air works with both Android and iOS, which is more in line with other Fitbit devices.

Before you make any final decision, it is important to remember that the Fitbit Air isn’t a medical device. Its sleep and heart rhythm features are for general wellness, not diagnosis. If you suspect sleep apnea or another clinical issue, the tracker is a conversation starter with your doctor, not an answer.

Compared to the premium-priced Whoop fitness tracker, the Google Fitbit Air is a budget-friendly device that lets you monitor your health, giving you greater control over tracking your daily fitness and wellness data.
