Features, uses and access

Name	Stardust
Overview	Stardust is a menstrual-cycle and pregnancy-tracking app from Stardust App LLC. It combines logged symptoms and cycle predictions with astrology-themed content. The provider describes AI-assisted insights, but this review did not establish that the app measures your estrogen, progesterone or testosterone levels. Hormone-related explanations and forecasts should not be mistaken for laboratory results.
Key features & benefits	Record cycle dates, symptoms and moods. Review predicted cycle phases and pregnancy-related information. Optional friend/partner sharing and supported health-data integrations. Stardust Super adds content such as horoscopes, tarot and a searchable cycle-information library.
Use cases and applications	Keep a record of symptoms and questions for a healthcare appointment. Compare your own notes over time without assuming a hormone caused every change. Explore astrology content separately from health decisions.
Who uses?	People interested in tracking a menstrual cycle or pregnancy, and partners invited to share information. Review eligibility and sharing settings before use.
Pricing	A free version and paid Stardust Super subscription are advertised. The US App Store lists multiple in-app purchase offers, not one universal price. Check the selected plan, currency, trial eligibility and renewal terms before subscribing. Trials may convert to recurring paid subscriptions unless cancelled; app-store purchase conditions can also apply.
Tags	Menstrual cycle tracker, symptom journal, pregnancy tracker, wellness app, astrology
App available?	Yes: the US iPhone listing was retrieved. The provider also describes Android support, but the exact native Google Play link could not be retrieved in this review. Feature availability may differ between platforms; no app was installed.

Use the tracker as a record, not a diagnosis

A practical example is to note when a symptom occurred and prepare questions to discuss with a clinician. This is a suggested workflow, not a test of Stardust. Do not treat horoscopes or tarot as clinical evidence or use cycle forecasts as contraception. The developer’s App Store description explicitly says the app is not a substitute for medical advice, diagnosis or treatment. No improvement in health, fertility or productivity was verified.

Check sensitive-data settings

The privacy policy describes health-data collection and service-provider access, with contact information stored separately from health records. It also distinguishes health data from device/activity information used for advertising with consent. These are provider statements, not an independent security audit or a promise of no sharing. Consider what to log and whom to invite before sharing cycle information.
