Give Young Women a Safe, Values-Driven Fertility App

Millions of girls and young women download cycle-tracking apps hoping to learn about their bodies. Instead, they’re met with data mining, targeted ads for contraception and abortion pills, and hyper-sexualized content. They deserve better.

PeakDay is a safe, private alternative as a modern, science-based cycle-tracking app built around privacy, dignity, and trusted information.

Why Your Support Matters

Apps in the FemTech industry reach tens of millions of young users. Many collect personal health data and expose teens to content that shapes their views on identity, sexuality, and relationships. PeakDay is growing — reaching more than 200,000 users through grassroots efforts — but we need help to scale quickly and offer a true safe alternative.

Your Gift Will Help Us:

  • Build AI-powered personalized cycle insights
  • Offer a free, safe version for teens and young women
  • Improve design and user experience
  • Expand integrations with wearables (Oura, Apple Watch, etc.)
  • Create more educational resources for families
  • Provide premium access for users who cannot afford it

Help Us Protect Teens and Empower Women

Your support creates a healthier, safer digital environment for girls and young women.
