inne detects progesterone in your saliva

The inne minilab is the first in the world to measure progesterone changes in saliva. To achieve this, the inne minilab uses the combination of highly sensitive immunoassays and advanced image processing technology to detect the smallest differences in hormone levels.

At the beginning of your menstrual cycle, your progesterone levels are low. They rise right after ovulation and remain high during your luteal phase. The inne minilab detects this rise and lets you know that ovulation has taken place.

Your cycle, your hormones

The rhythm of a woman’s menstrual cycle is controlled by several hormones. At the end of the follicular phase, estradiol briefly peaks, triggering the brain to release luteinizing hormone (LH). This LH spike activates a series of events that result in the release of the egg from the matured follicle in the ovary. This is known as ovulation. Following ovulation, the follicle develops into the corpus luteum, which is responsible for producing the hormone progesterone.

Progesterone concentration increases during this time, peaking in the mid-luteal phase. During the late luteal phase, the progesterone concentration begins to decrease.
By monitoring progesterone levels across your cycle, the inne minilab is able to identify user’s ovulation day, creating a personalized fertility prediction.

Tap into the power of your hormones.

Tracking your cycle can allow you to get the best from your body on any given day.

Meet the minilab

What can I learn from my progesterone levels?

Unlock all this information with just a few drops of saliva.

Your fertile window

Your fertile window

The inne minilab predicts the days in your cycle when you are able to get pregnant, taking into account the predicted day of ovulation, sperm survival, and for the possible variability of the ovulation day.

Ovulation day

Ovulation day

Ovulation occurs directly between the follicular and luteal phases. The inne algorithm not only predicts, but also confirms it by detecting the characteristic rise in progesterone that follows your ovulation.


Your Progesterone Trend

The inne minilab tracks your progesterone levels across your menstrual cycle, pinpointing the change between your follicular and luteal phases. You can track your hormonal fluctuations in real-time to better understand what they mean.

Insights into your cycle

Insights into your cycle

The inne app puts your daily hormone reading in context and provides you with additional insights that help you understand your cervical fluids and menstrual cycle symptoms.

inne is not certified for contraceptive use.

inne is sensitive

The inne minilab is able to detect really tiny hormonal changes in saliva. In one milliliter of saliva, the inne minilab is able to detect the change of 0.0000000001 grams of progesterone.

Although these concentrations may seem very small, they trigger substantial physiological changes, such as ovulation.

The inne minilab is the only device that allows you to measure such small hormonal changes without leaving your house. Up until now, there was no way to measure your hormonal levels at home, instead, you had to send your saliva to a lab. With the inne strips and the inne reader, you can now do that daily in the comfort of your own home. Giving you a full overview of your hormonal cycle rather than a snapshot.


Transforming hormones into insights

Daily hormonal readings rarely create as smooth curves as we are taught in textbooks. Instead, your progesterone measurements fluctuate along the menstrual cycle's hormonal curve.

Our algorithm takes this natural variability into account by defining a hormonal baseline during the follicular phase of each cycle.

In every ovulatory cycle, progesterone distinctly rises at the beginning of the luteal phase. The inne algorithm identifies this rise, creating a pronounced and reliable benchmark to confirm that the transition from the follicular to the luteal phase has taken place. This transition marks ovulation.

Hormones in your saliva accurately reflect the hormones in your body

Hormones in your saliva accurately reflect the hormones in your body

Saliva may not be the first thing you think of when you think of your hormone levels. Here at inne, we want to change that. Our goal is to harness the simplicity of a once-a-day saliva test. No needles, no blood, no urine.

You may not regularly think about the molecules in your saliva, but that doesn't mean they aren't there! Sex hormones in your saliva are an accurate depiction of your physiological hormone levels. Hormone concentrations in saliva remain constant relative to their level in blood.

Hormones are the invisible force that shapes our body's feelings and behaviors. With inne, they are now visible and you can take a look.
