Why I built a fasting app that bends with women's hormonal cycles

Hi Product Hunt! 👋 I'm Samantha Linden, MEd, DBA. A women's wellness coach and meditation teacher, and the founder of Hormone-Smart Rhythm.

For years, I watched women try fasting plans built for an 18-24-hour male hormone cycle. Pushing rigid fasts right before your bleed spikes cortisol, drains energy, and leads to burnout. I built Hormone-Smart Rhythm so fasting bends with your cycle instead of fighting it. You get a personalized daily fasting range and nourishment focus—whether your cycle is regular, irregular, or paused.

Members get a 30-day customized calendar they can actually print out or save in the app, and every member can message me directly in the app—I answer each one myself.
