When Discomfort Interrupts Your Day
For many women, monthly cramps can affect focus, productivity, sleep, and movement.
While medication is one option, many women seek non-drug support that fits naturally into their routine.
Rosi® was created as a modern, wearable solution designed to move with you.
Getting Started with Rosi®
How Rosi® Works
What Is TENS?
TENS (Transcutaneous Electrical Nerve Stimulation) is a safe, non-invasive technology widely used to help relieve pain.
How Rosi® Uses TENS for Menstrual Comfort
Rosi® delivers gentle electrical pulses to the lower abdomen to help calm pain signals before they reach the brain.
This stimulation may also support the release of endorphins — your body’s natural comfort response — helping to ease cramps and discomfort.

What Our Customers Say
The Rosi period pain device provides comfort and relief during challenging times, empowering women to lead healthier, more active lives. Here is what our customers say:
“I usually relied on painkillers for menstrual pain, but they often made me sleepy and affected my concentration. After using Rosi, I didn’t need to take painkillers anymore. The pain went away quickly, and I could work and go about my day normally without feeling uncomfortable. I also didn’t experience any side effects, which made me feel safe using it.”
“I found Rosi easy to set up and comfortable to use, even while working or moving around. It helped relieve my menstrual pain effectively, especially when I used it at the first sign of discomfort. I didn’t need to rely on painkillers as much as before, and I appreciated being able to adjust the intensity to suit my condition. Overall, it was practical, easy to use, and fit well into my daily routine.”
From a women’s clinic in Japan
“For young girls who don’t feel comfortable relying only on medication-based treatments, having another option makes a real difference.
When mothers see their daughters try Rosi and feel comfortable with it, they feel reassured..”
“I have tried many ways to manage menstrual pain over the years, including painkillers, hormonal options, and other treatments, but none worked consistently. With Rosi, the pain eases quickly when I use it, and while the pain may gradually return after removing it, it is much easier to manage. I was able to reduce how often I take painkillers, and I felt reassured using it because it is a medical device. Being able to use it at home or at work made it practical for my daily life.”
