Google just redefined what a health wearable is with the launch of the Fitbit Air: a screenless tracker, with AI integrated via Gemini Health Coach, available at an entry price of USD 99. It's Google's most ambitious bet in the health tracking market and goes directly to compete with WHOOP, the favorite device of athletes and high-performance professionals.

When a platform with Google's reach integrates a conversational language model into health monitoring, the implications go far beyond counting steps. Here we explain what the Fitbit Air does, how it differs, what data it tracks, and what it means for LATAM users.

What the Fitbit Air is and why it has no screen

The Fitbit Air is Google's bet on making health tracking completely invisible. No screen, no buttons, no wrist notifications. The interaction happens 100% from the app on the phone, where Gemini Health Coach processes all the data and turns it into conversational insights and personalized recommendations.

The decision to eliminate the screen is strategic: it reduces the cost of the device to USD 99 (vs the USD 239 of the WHOOP 4.0), extends the battery, and puts the focus on health data instead of hardware. The official launch is scheduled for May 26, according to TechCrunch, with availability in the United States first and gradual expansion to other regions.

Gemini Health Coach: your personal health AI

The key difference of the Fitbit Air compared to any other wearable on the market is Gemini Health Coach. It's not an assistant that shows charts: it's a language model that processes your health data in real time and can answer questions like "why did I sleep poorly this week?", "what does my HRV say about my recovery level?", or "when is the best time to train today?".

Gemini Health Coach has access to the entire device history and can correlate variables that no static dashboard can easily connect: how sleep impacts heart rate variability, how stress affects blood oxygen level, or what patterns repeat before an episode of fatigue. According to Engadget, Google aims for the device to be the first truly conversational wearable in the mass market.

What health data the Fitbit Air tracks

The Fitbit Air monitors a set of metrics of high clinical value:

• Afib (atrial fibrillation): detection of irregular heart rhythms with real-time alerts.

• SpO2 (blood oxygen saturation): continuous monitoring during sleep and activity.

• HRV (heart rate variability): the most precise indicator of recovery and stress level of the autonomic nervous system.

• Sleep phases: REM, deep sleep, light sleep, and awakenings, with comparative analysis vs personal averages.

• Stress level: measured through electrodermal activity (EDA) and HRV.

• Skin temperature: useful for detecting early signs of illness or hormonal cycles.

The subscription model: the key to the business

The Fitbit Air requires a subscription of USD 9.99/month to access the premium features of Gemini Health Coach and the advanced analysis. Without a subscription, the device records basic data but without the AI analysis. This model —cheap device, subscription for the real value— is Google's bet to create recurrence and compete head-on with WHOOP, which charges USD 30/month for its recovery and performance analysis.

For the end user, the equation is clear: in the long term, the total cost of the Fitbit Air is lower than that of WHOOP, but the bet on AI is what defines whether the value proposition holds up.

Health data privacy: the inevitable question

When Google collects data on Afib, SpO2, sleep phases, and stress patterns, the question about privacy is inevitable. Google Health has a history of controversies on this point (the Nightingale project in 2019 generated debate), and the massive adoption of this type of device in LATAM will depend in part on how much trust the company generates in handling sensitive health data. The terms and conditions of the service in each country are the first place where users should review what data is shared and with whom.

What it means for LATAM

Google has massive penetration in Latin America, both in Android and in its suite of products. A health wearable at USD 99 —accessible versus the USD 400+ of an Apple Watch with similar features— has real potential for massive adoption in markets like Argentina, Brazil, Mexico, and Colombia. The key is the regional availability and the support of Gemini Health Coach in Spanish.

In addition, this move by Google consolidates the trend of recent years: AI is not only arriving in work and creativity, but also in the body and health.

Frequently asked questions

Does the Fitbit Air work with iPhone?

Yes. Although Google is the company behind Fitbit, the device is compatible with iOS and Android. The Fitbit app is available on both platforms, although the integration with the Google ecosystem is smoother on Android devices.

Is the Fitbit Air's Afib detection medically certified?

Google has sought FDA certifications for the Afib detection functionality. However, like all wearables on the market, the Fitbit Air is a wellness device and not a medical device. Its data is indicative and does not replace a professional medical diagnosis.

Do I need the subscription for the device to work?

You can use the Fitbit Air without a subscription, but with limited functionalities: basic activity, heart rate, and sleep tracking without the advanced Gemini Health Coach analysis. To access the AI recommendations, correlations between metrics, and recovery analysis, the USD 9.99/month subscription is necessary.

When does the Fitbit Air arrive in Argentina and LATAM?

The initial launch is in the United States with availability in May. The expansion to LATAM markets depends on Google's distribution plans and local medical/wellness device regulations. Historically, Google takes between 6 and 18 months to bring its hardware products to Argentina and the region.

Is the Fitbit Air worth it if I already have a smartwatch?

It depends on the type of smartwatch. If you have an Apple Watch Series 9 or a Galaxy Watch, you already cover much of the Fitbit Air's metrics. The Fitbit Air's differentiator is the price, the battery life, and, above all, the conversational analysis of Gemini Health Coach. If your current smartwatch doesn't have continuous HRV or detailed sleep analysis, the Fitbit Air can be a good addition or replacement.
