inne is currently a good fit for women who for the last three months can relate to these criteria
During pregnancy, you do not have a menstrual cycle. Therefore you should wait until the second consecutive period after the end of the pregnancy, even if the pregnancy was not carried to term before starting to use inne.
When breastfeeding, your hormone levels might fluctuate and your menstrual cycle is not regular. Therefore you should wait until the second consecutive period after you stopped breastfeeding before starting to use inne.
Medical treatments that can affect your cycle, should indicate so in the patient information leaflet of the respective medication. The inne minilab measures how your progesterone behaves during the menstrual cycle. If our menstrual cycle is affected due to another treatment we won’t be able to provide you with accurate evaluations.
If you suffer from PCOS, your hormonal cycle might not be regular and this might affect the accuracy of your system. We hope we will be able to support women who have polycystic ovarian syndrome in the future.
If you suffer from endometriosis, your hormonal cycle might not be regular and this might affect the accuracy of your results. We hope we will be able to support women who have endometriosis in the future.
Menopausal symptoms can be hot flashes and night sweats. During menopause, your hormone production decreases and can fluctuate. We hope we will be able to support women during menopause in the future.
For now, we can ensure the accuracy of the results for cycles between 22 to 35 days long. We are always working on making our system available for a wider variety of cycles. Please note that inne can only provide accurate results when you add correct dates during the inne APP onboarding.
The inne minilab is a medically certified system for fertility monitoring. It is intended for women above 18 years old.
Hormonal contraception affects your natural hormone levels. You should have had two consecutive cycles after you stopped using hormonal contraception before you start using inne.
