WiStim is not a period-tracking app. It is a dedicated tool for women and couples undergoing fertility or ART treatments: IVF, insemination, ovarian stimulation, egg freezing (fertility preservation), or trying to conceive. Designed by fertility and reproductive specialists alongside recognized ART experts, WiStim currently supports over 200,000 users and is used in leading French and international fertility centers.

A More Peaceful Fertility Journey

Understand: Detailed video tutorials for every step of your protocol (egg retrieval, stimulation, embryo transfer...), clear explanations of treatments, medical jargon, and journey milestones. Demystify the process and take back control of your baby plans.

Stay Organized: A personalized calendar for treatments and appointments, automatic reminders so you never miss an injection or medication, and a centralized hub for prescriptions, lab results, and medical documents.

Reduce Stress: Fewer treatment errors, less mental load, and more peace of mind every day. Reliable guidance at every stage to move forward with confidence, whether you are on your own or with a partner.

An App That Adapts to Your Journey

WiStim can be used completely independently: you can track your fertility, manage your treatments, and access all content, whether you are just starting to think about it, trying to conceive, or already in a medical protocol.

Is your doctor or fertility clinic also using WiStim? Your app connects directly with them. You then benefit from shared monitoring, secure communication with your medical team, and direct access to your results. One tool, two levels of support, tailored to your situation.

Who Is It For?

WiStim is for all women and couples navigating fertility and ART: heterosexual and same-sex couples, single mothers by choice, or anyone exploring their fertility or already engaged in an ART protocol.
