The system
One cycle was never meant to be supported in one way.
Four phases. Four formulas. One connected system. 28four pairs four phase-specific formulas—Menstrual, Follicular, Ovulatory and Luteal—with a cycle-tracking companion app.
The 28four app moves through your cycle with you — tracking your phase and reminding you which formula to take, and when. Log your energy, mood and symptoms to build a clearer picture of your own rhythm over time.
