What it does
Stardust is a period and pregnancy tracking app that merges scientific health data with astrology and lunar cycles. It provides users with daily, personalized insights into their hormonal fluctuations, moods, and symptoms, all framed within a mystical, cosmic theme. The app aims to help users understand their body's patterns by syncing them with the cycles of the moon.
Where it shines
Stardust stands out by committing fully to its astrological aesthetic. The onboarding is a great example, where a standard birthday request becomes an interactive zodiac picker with animated constellations (00:36). The main dashboard (02:58) is another highlight, presenting a beautiful, circular visualization of the user's cycle mapped to moon phases. This scrubber is not just for show; it's an interactive tool for exploring insights across the month (03:25), making data exploration feel intuitive and immersive.
UX highlights
- Thematic UI: Standard components are redesigned to fit the cosmic theme. The period-logging calendar (01:05) uses moon phases instead of a grid, reinforcing the brand in a core interaction.
- Conversational Insights: The app delivers 'Daily Decodes' (04:23) that explain hormonal changes in a playful, narrative style, making complex biology feel accessible and engaging.
- Symptom Logging: Adding symptoms (05:40) is straightforward. Tapping an icon opens a panel to specify intensity with a slider, providing granular data without a complex form.
- Partner Mode: The app includes a 'Partner Mode' (06:44) that allows users to share cycle insights with a partner, turning a personal utility into a shared communication tool.
- Layered Information: Users can get a high-level overview on the main dashboard or tap into sections like 'Mind' (04:33) or 'Body' (04:56) for detailed, day-by-day explanations and animations.
Monetization & growth
The app presents a soft paywall at the end of its onboarding quiz (02:30). It offers a 7-day free trial for an annual plan, highlighting a 64% discount and breaking the cost down to a monthly price. A full-price monthly option is also available. The paywall cleverly uses a visual timeline to explain when the user will be reminded and when the trial ends, which builds trust. Growth is also driven by the native 'Partner Mode' (06:50), which encourages users to invite others to the platform.
Who it’s for
Stardust is for individuals who want to track their menstrual cycle but are looking for an experience that goes beyond a purely clinical or medical feel. The target user is likely interested in astrology, mindfulness, and holistic wellness, and appreciates a beautifully designed, narrative-driven app. It appeals to those who want to feel more in tune with their body's natural rhythms and see them reflected in larger cosmic cycles.
Notes & opportunities
The onboarding flow is quite long, with numerous questions and permission requests before the user reaches the main app. While this allows for deep personalization, it could also be a point of drop-off for users seeking immediate utility. The main dashboard is visually rich, but the sheer amount of information and tappable elements could initially feel slightly overwhelming. Simplifying the hierarchy or offering a guided tour upon first entry could help orient new users more quickly.
