Garmin Fans Can Now Unlock Fertility Insights on Their Wrist Thanks to New Natural Cycles Partnership

2 weeks ago

Garmin has long been known for producing some of the best fitness-focused smartwatches and wearables on the market. From serious athletes to everyday users, Garmin devices excel at tracking runs, cycles, swims, sleep, recovery, and overall health metrics. Now, the company is expanding its health capabilities even further by adding fertility tracking through a new partnership with Natural Cycles.

This feature brings non-invasive, convenient cycle and fertility insights directly to your wrist on many popular Garmin models, including the Fenix 8, Forerunner 570, Venu 4, and Venu X1. By measuring skin temperature overnight and syncing the data to the Natural Cycles app, users can gain a clearer understanding of their reproductive health, menstrual cycle patterns, and fertility windows — all without additional hardware or invasive methods.

Natural Cycles is the only birth control app cleared by the FDA, giving it strong credibility in the fertility tracking space. The integration with Garmin wearables makes the process seamless and non-disruptive, fitting perfectly into the daily routine of active users who already rely on their Garmin device for fitness and health monitoring.

In this detailed guide, we explore how the new fertility tracking feature works, which Garmin devices support it, its benefits and limitations, how it compares to similar features from Apple, Whoop, Fitbit, and others, and what it means for Garmin’s position in the health and wellness wearable market in 2026.

The new feature is elegantly simple and non-invasive:

Your compatible Garmin watch tracks skin temperature overnight while you sleep.
In the morning, the data is automatically synced to the Natural Cycles app on your phone.
The app analyzes the temperature data alongside other cycle information (if provided) to provide personalized fertility insights, ovulation predictions, and cycle tracking.

This approach leverages Garmin’s already excellent sleep and physiological tracking capabilities. Many Garmin watches already monitor body temperature variations as part of their recovery and health metrics, so adding fertility insights feels like a natural extension rather than a completely new capability.

Key Benefits:

Convenience — No need for additional sensors, basal body temperature thermometers, or manual logging.
Non-Invasive — Just wear your watch as usual.
Privacy-Focused — Data is handled securely between Garmin and the Natural Cycles app.
Actionable Insights — Helps users better understand their cycle, plan or prevent pregnancy, or simply track reproductive health.

The feature is currently available in select regions: Australia, Brazil, Canada, the European Union, Norway, Singapore, Switzerland, the United Kingdom, and the United States. Garmin has not yet announced a wider global rollout timeline.

The fertility insights feature is rolling out to many of Garmin’s most popular and capable wearables, including:

Fenix 8 series — Garmin’s flagship multisport watches
Forerunner 570 — Popular running-focused model
Venu 4 and Venu X1 — Lifestyle-oriented smartwatches with strong health tracking

This wide availability means a large portion of the Garmin user base can benefit from the new capability without needing to buy a new device. Garmin has confirmed that additional models may receive support in future software updates.

To use the feature, you’ll need:

A compatible Garmin watch with skin temperature tracking capability
The latest software update on your watch
The Natural Cycles app installed and linked to your Garmin account

Once connected, temperature data collected overnight is shared with Natural Cycles for analysis.

Garmin is not the first company to add fertility or cycle tracking to its wearables:

Apple Watch — Offers cycle tracking and temperature-based ovulation estimates through the Cycle Tracking app.
Whoop — Provides detailed cycle and recovery insights, especially useful for female athletes.
Fitbit (now part of Google) — Has robust period and fertility tracking features.
Oura Ring — Known for excellent temperature tracking and fertility insights.

Garmin’s approach stands out because:

It leverages existing hardware (no new sensors needed)
It partners with a clinically validated app (Natural Cycles)
It focuses on seamless integration for active users who already wear Garmin daily

The combination of Garmin’s accurate physiological sensors and Natural Cycles’ FDA-cleared algorithm creates a powerful, convenient solution for users who want reliable fertility insights without extra effort.

The fertility tracking feature is useful for a wide range of users:

Women planning pregnancy — Get better ovulation predictions and fertile window insights
Women using natural birth control — Track cycles more accurately with temperature data
Athletes monitoring hormonal health — Understand how training affects recovery and cycle patterns
Anyone wanting deeper health insights — Temperature variations can provide early indicators of overall wellness

Because the tracking happens automatically overnight, it fits naturally into daily routines without requiring extra steps or manual measurements.

While promising, the feature has some limitations to keep in mind:

Availability is currently limited to certain countries
Accuracy depends on consistent wear during sleep and good data quality
It works best when combined with other cycle information entered in the Natural Cycles app
Not a replacement for professional medical advice — always consult a doctor for fertility or health concerns

Users should also consider privacy implications when sharing health data between Garmin and the Natural Cycles app.

Garmin’s new fertility tracking feature, powered by its partnership with Natural Cycles, is a welcome addition to its already impressive health and wellness capabilities. By bringing convenient, non-invasive cycle and fertility insights to popular models like the Fenix 8, Forerunner 570, and Venu series, Garmin is making reproductive health tracking more accessible for active users.

The feature fits perfectly with Garmin’s focus on comprehensive, data-driven wellness tools that go far beyond simple step counting. While it doesn’t replace professional medical advice, it provides valuable insights that can help users better understand their bodies and make informed decisions.

As wearable technology continues to evolve, features like this highlight how devices on our wrists can support not just fitness goals but broader aspects of health and well-being.

If you own a compatible Garmin watch, the new fertility insights are worth exploring — especially if cycle tracking or family planning is important to you. Garmin continues to prove that smartwatches can be powerful health companions in 2026 and beyond.
