“Extremely comfortable, even more so than a smartwatch or smart ring.”
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.

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.

Pay with HSA/FSA
We've partnered with Flex to enable customers to check out with their Health Savings Account (HSA) or Flexible Spending Account (FSA) card.
HSA/FSA Frequently Asked Questions
Yes. Petal works with Flex so you can pay with your HSA or FSA card. Because that money is set aside pre-tax, you effectively save around 30% versus paying with a regular card. Just choose the “Flex - Pay with HSA/FSA” option at checkout. If you don’t have your HSA/FSA card handy, you can pay with a credit or debit card and submit for reimbursement later, or split your purchase if you don’t have enough funds.
An HSA (Health Savings Account) and an FSA (Flexible Spending Account) both let you set aside pre-tax money for qualified health expenses, so using them is like getting a built-in 30% discount on eligible purchases. The main difference is that an HSA is yours for life, rolls over every year, and pairs with a high-deductible health plan, while an FSA is employer-owned and usually has a year-end “use-it-or-lose-it” deadline. Either way, you can use the card the same way to check out with Flex.
Flex is available for eligible customers; HSA/FSA savings vary based on individual circumstances and eligibility. Learn more at withflex.com/disclosures.
Add items to your cart and proceed to checkout. Select “Flex - Pay with HSA/FSA” as your payment method, enter your HSA or FSA debit card, and check out as usual. If you don’t see the Flex option, you may be in Shop Pay, so choose “check out as guest” to see all payment methods.
It depends on the account. HSA funds roll over indefinitely, so they’re yours to keep. FSA funds often follow “use-it-or-lose-it” rules and may expire at year-end or after a short grace period, so it’s worth using them before your deadline.
