Understand your sensations through data.

This smart pleasure item visualizes changes in your pelvic floor muscles and bodily responses via an app.

LIONESS is a smart pleasure item that records contraction patterns of the pelvic floor muscles and vaginal area, visualizing them as graphs in a dedicated app.

Pleasure is often described vaguely, based solely on sensation. LIONESS helps you understand your body by recording changes in bodily responses with its built-in sensors and reviewing trends from each session.

For those who want to view self-pleasure not just as a mood change, but as "self-care for understanding one's own body." This is an app-linked femtech device that connects sexual wellness with technology.

Target: 18 years and older

Why fermata carries Lioness

At fermata, we believe that pleasure is not about conforming to someone else's standards, but a crucial part of wellness for understanding one's own body and responses. Lioness is a device that allows you to review your body's responses as data, creating an opportunity to explore what feels good to you.

We resonate with how Lioness provides more clues to understanding oneself, even when it's difficult to articulate sensations, which is why we carry it.

Lioness

Lioness is a femtech brand founded in California, USA in 2014. The founder began development with the desire to "create an option to objectively understand one's own body, rather than relying solely on sensation," inspired by her personal experiences.

This aspiration led to the creation of smart pleasure devices that measure pelvic floor muscle and vaginal contractions, visualizing orgasm. Two sensors in the device record bodily responses, which can be viewed as waveform graphs on a dedicated app. A key feature is its design, which prioritizes safety and comfort, using medical-grade silicone.

As a product that allows users to review pelvic floor muscle movements and body rhythms through data, it has garnered global attention and been featured in major international media. In Japan, official distribution began in 2026 through fermata, which promotes the social implementation of femtech centered on women's health.

Lioness is a brand that connects technology with intimacy, proposing a new form of self-care that progresses from "feeling" to "understanding."
