1. Summary of Key Findings

• Regulatory Positioning:

  • Only Clue and Natural Cycles have FDA clearance as contraceptive devices.

• Usability & Features:

  • Accuracy is a core differentiator, but user input quality limits reliability.
  • Partner-sharing, wearables integration, and teen-focused apps show expanding user expectations.
  • Users frequently complain about monetization prompts and intrusive notifications.

• Privacy & Safety:

  • Strong public concern about sensitive reproductive data, especially in the U.S. context of abortion politics.
  • Experts stress need for transparent consent, pseudonym options, and minimization of personal data collection.
