An age range helps researchers to identify the data important to them while keeping us GDPR compliant and your identity safe (we’ll never ask for your specific age).

3

We offer the most comprehensive enthic list to choose from, ensuring that all women are included.

4

Help researchers understand where in the world you are while remaining GDPR protected (we’ll never ask for more than your country).

5

Select any conditions you’ve identified (clinitian-diagnosed or self-diagnosed), medications you are taking (including vitamins or contraception), and any modalities you’re trying. This helps Astra personalize your experience and researchers find the right data.

6

Though pregnancy is a pivotal event in life, it is also politically dangerous for some women to talk about. That’s why we made this field optional.

You’ve tracked your period. Now track the rest.

Most female tracking apps focus on cycles. Ours tracks the rest — pain, fatigue, mood, memory, and the symptoms no one else studies. Built by women, for women, backed by science.

Why Use Astra

  • Learn About Your Body

    Astra remembers you had a headache last week and three weeks ago — and the factors that may have played a role. Over time, she’ll advise you to help improve your health. She’ll even provide a clincian readout (rather than a vague chart) to help you communicate with your doctor.

  • Meaningful Impact

    Your life improves while you contribute to research. Your responses are pooled with those of women around the world to teach researches exactly what it’s like to be a woman. Let’s address long-ignored gaps in women’s non-reproductive health together.

  • Data Privacy

    We use cryptography at every stage. All responses are anonymized to protect your identity and you can request to remove your data at any time (even ten years from now).

I was amazed by the depth of ethnic coverage the app provides. Feminine health is not only largely ignored, it’s not approached by sensitive genetic markers that can create vital clues for progress in non-reproductive health in regards to disease, sensitivities, etc. The geographical data will be an invaluable tool in forecasting and finding trends, no doubt leading Asterisk to continue to grow as leader and force for change for feminine health.

Asterisk wants to acknowledge the use of the term “women” as a term that has been both inclusive and exclusive of trans, assigned-female-at-birth (AFAB), intersex and others who have been discriminated by traditional Western medicine. We are currently using the term over other intersectional terminology (womxn, FLINTA*, etc.) to ensure the continuity of data collection from a biological sex perspective.
