Key Takeaways

  • Core Features: Daye provides period tracking combined with personalized hormone testing and wellness insights focused on menstrual health.

  • Design & Inclusivity: Modern and clean design targeting cisgender women; some efforts toward inclusive language but limited non-binary support.

  • Data Handling: Collects sensitive hormone data with GDPR compliance; privacy policy is clear but could improve transparency on data sharing.

  • Verdict Summary: Useful for women seeking personalized hormone insights alongside period tracking but could expand inclusivity and clarify data usage.

Medical Integrity

Score: ⭐⭐⭐☆☆

Daye partners with clinical labs for hormone testing and provides medically informed content. However, some health recommendations could benefit from more direct clinician involvement and transparency.

Doctor’s Note:
The app offers solid hormone tracking tools but should strengthen clinical oversight and clarify test limitations for users.

Ethical Standards

Score: ⭐⭐⭐☆☆

Clear consent for testing and subscriptions, with upfront pricing. Some marketing leans heavily on wellness trends, which may confuse users about medical validity.

Doctor’s Note:
Ethical in consent and pricing, though marketing could better distinguish between wellness and medical claims.

Data Privacy & Protection

Score: ⭐⭐☆☆☆

Daye complies with GDPR but shares some anonymized data with partners. User control over data is limited, and privacy notices could be more accessible.

Doctor’s Note:
Users should be aware of the scope of data use and have clearer control options to build trust.

UX & Accessibility

Score: ⭐⭐⭐☆☆

App is easy to navigate with engaging design but lacks comprehensive accessibility features. Language support is minimal.

Doctor’s Note:
Good initial UX but should invest in wider accessibility and inclusivity enhancements.

Behavioral Impact

Score: ⭐⭐⭐☆☆

The app encourages healthy lifestyle changes with reminders and insights, though some features require paid subscriptions, which may limit behavior change impact.

Doctor’s Note:
Supports positive habits but should avoid paywall barriers that might exclude users.

Final Score: ⭐⭐⭐☆☆ (3/5 stars)

Verdict:
Daye is a promising tool for women interested in combining hormone testing with period tracking but needs to improve clinical transparency, data privacy, and inclusivity to fully serve diverse users.
