Women’s health is fragmented, poorly understood, and reduced to cycle tracking by almost every tool on the market. Ovum is designed to be different, clinically credible, emotionally intelligent, and useful every single day.
Ovum is a longitudinal health companion, that adapts in real time to symptoms, goals and life stages. Providing women a complete picture of health that holds up in any clinical setting. A true health partner women can take into any appointment and be believed.
When you use Ovum, you’re fuelling a longitudinal health study for womenkind, helping researchers understand how medications interact with the female body, while giving doctors the insight to care better.
Together, we’re building a better system that includes women in their story.
