The wearable built just for women.

Most wearables are designed for men. We designed ours for you — placed over the heart, for a better understanding of your body.

Metrics that matter.

A fuller picture of your health, beyond heart rate and steps.

Mobility & Balance

Strength gets the spotlight, but balance and mobility are what keep you doing the things you love. Both shift slowly with age, and Petal helps you keep an eye on it.

Visceral Fat

Not all fat is the same. Visceral fat sits deep around your organs and plays an outsized role in how your body handles energy and inflammation. Petal shows you the difference.

Heart Health

Your heart rate shifts with hormones, stress, and activity, in patterns that reflect how well you're recovering. Petal tracks those changes over time for real insight into your resilience.

Activity

Your energy isn't constant. It rises and falls with your cycle, sleep, and training. Petal shows how much you move and how hard, so you know when to push and when to back off.

Why women love Petal.

What makes Petal different.

  • Built for women first

    Most wearables are designed for men. We designed ours for you — discreet and placed over the heart, for a better understanding of your body.

  • See what others can't

    Petal can track your walking patterns and body composition, including visceral and midsection fat, for a fuller picture of your health.

  • Safety you can verify

    Designed for everyday wear. Petal uses Bluetooth® Low Energy, not Wi-Fi or cellular, and materials are OEKO-TEX® STANDARD 100 certified.

  • Create a better future for women

    Women's health has been understudied for decades. With your permission, your data helps build the research foundation women's health has been missing.

What the press is saying

I found it very comfortable, and it’s easy to forget you’re even wearing it.

— Rena, Everyday Health

Unlike other wearables that rely on light-based sensors or indirect basal temperature readings, Petal uses medical-grade bio-impedance and electrical measurements to deliver insights on the heart, mind, body and cycle.

— Athletech News

I tried it on at CES and found it extremely comfortable, even more so than a smartwatch or smart ring.

— Angela, PC MAG  

Because wearers position the insert right next to the heart, the device can capture more accurate readings than your typical smartwatch.

— Nina, ZDNET

Designed for comfort and discretion, it [Petal] brings preventive monitoring into daily life.

Frequently asked questions

No. Petal has no Wi-Fi or cellular radios. It uses only low-power sensing technology and safely uses Bluetooth® Low Energy to communicate with the Petal Wellness™ mobile app, and it emits no ionizing radiation.

  • No. Petal is a wellness device designed to help you understand your body- it is not a medical device, and it does not replace emergency medical care or advice from a healthcare professional.
  • This product is not intended to diagnose, treat, cure, or prevent any disease.
  • Yes. Petal is one size.
  • It's a thin insert that lies flat against your chest rather than filling the cup, so it works across sizes. Sensors are on the left insert, and they need snug contact to read accurately — so wear it with a close-fitting bra, bralette, sports bra, or built-in-bra top.
  • No. Petal's sensors need direct contact with your skin, so wear it between your breast and your garment.
  • Placing it inside a fabric pocket will block the sensors.
  • A Petal Wellness™ membership is required to unlock your insights in the app.
  • Right now, a 12-month membership is included with your Petal purchase.
