Stardust ⭐⭐⭐⭐
Key Takeaways
Core Features: Tracks menstrual phases (follicular, ovulatory, luteal, menstrual), symptoms, mood, and lifestyle prompts; integrates lunar syncing and partner/friend sharing.
Design & Inclusivity: Stylish visuals, personalized daily insights with humor; limited support for irregular cycles and non-binary preferences.
Data Handling: End-to-end encryption, anonymized by default, GDPR-aligned; voluntary data-sharing with authorities removed, but third-party involvement remains minimally transparent.
Verdict Summary: A visually engaging, privacy-forward cycle tracker with thoughtful features—but has stability issues, irregular-cycle limitations, and isn’t fully inclusive.
Medical Integrity
Score: ⭐⭐⭐☆☆
Stardust logs cycle phases and symptoms accurately for many but lacks peer-reviewed validation for health guidance. It blends astrology and cycle awareness, which isn't clinically standardized.
Doctor’s Note:
“Stardust raises cycle awareness but shouldn’t substitute for medical tools—especially if users have PMDD, PCOS, or irregular periods.”
Ethical Standards
Score: ⭐⭐⭐⭐☆
No in-app ads or hidden monetization. Encourages partner connectedness and daily self-reflection. However, humor and tone may feel trivial or insensitive for some users.
Doctor’s Note:
“Ethically respectful and thoughtfully designed. Tone balance could be adjusted to avoid alienating people during emotional cycle phases.”
Data Privacy & Protection
Score: ⭐⭐⭐⭐☆
Stardust uses end-to-end encryption and anonymization. It removed voluntary data-sharing with law enforcement, though still may respond when legally compelled. Some third-party data practices lack full transparency.
Doctor’s Note:
“Strong privacy stance for sensitive data. Enhanced clarity about who accesses anonymized data and retention timelines would foster greater confidence.”
UX & Accessibility
Score: ⭐⭐⭐☆☆
Beautiful aesthetic and intuitive daily logging. Experience is marred by Android crashes, sync issues, and no support for customizing symptoms or accommodating non-normative cycles.
Doctor’s Note:
“Visually engaging, but functionality must improve. Better stability, inclusive customization, and accessibility options are essential for reliable use.”
Behavioral Impact
Score: ⭐⭐⭐⭐☆
Encourages self-awareness, planning, and partner engagement. Tracks onward behavior without upselling, but humor-driven notifications can feel tone-deaf for some.
Doctor’s Note:
“Stardust promotes mindfulness and cycle connection. However, users with serious emotional symptoms may need more clinical support than the app offers.”
Final Score: ⭐⭐⭐⭐☆ (4/5 stars)
Verdict:
Stardust is a creatively designed, privacy-conscious cycle tracker that resonates through lunar syncing and partner sharing. It scores high in emotional engagement but falls short in clinical depth, inclusivity, and technical stability. Best as a lifestyle companion rather than a medical tool.
