Astraea 3.0: Rebuilt from the ground up for PCOS. Honest cycle confidence, 126 symptom chips, glycemic meal scanner, and clinical evidence. Try Full free for 7 days. Astraea is an honest, evidence-based cycle and symptom record designed from the ground up for Polycystic Ovary Syndrome (PCOS) and Polyendocrine Metabolic Ovarian Syndrome (PMOS). Standard cycle trackers assume a predictable 28-day rhythm. When an irregular cycle runs 45 or 60 days, countdowns turn red, streaks break, and algorithms guess. Astraea is built on a different doctrine: your body is not broken, variation is biological data, and an application should never pretend to know what your body has not yet signaled. KEY FEATURES • CONFIDENCE-LAYERED CYCLE ENGINE Astraea calculates variation from your genuine recorded cycles. When variability exceeds predictable thresholds, Astraea refuses to fabricate arbitrary dates. Instead of false certainty, you see honest probability windows anchored in your real biology. • COMPREHENSIVE SYMPTOM & BIOMARKER LOG Track what matters across 12 distinct categories and 126 specialized chips: - Hormonal acne, hirsutism, hair shedding, and androgen signals - Fatigue, brain fog, and reactive glucose dips - Bloating, digestive shifts, and pelvic sensations - Sleep quality, basal body temperature (BBT), and LH ovulation tests - Daily water intake with customizable glass targets and weight trends • GLYCEMIC LOAD MEAL SCANNER Snap a photo of your plate or describe your meal. Astraea evaluates overall glycemic load and checks against your personal "Keep-out" list. Designed for insulin awareness and steady energy — no calorie shaming, no restrictive diet dogmas. • 32 CLINICALLY SOURCED READINGS Access clear, open-access clinical insights cited directly from Monash University international guidelines, the Endocrine Society, and Cochrane systematic reviews. Every reading declares its evidence level (Strong, Moderate, or Limited) and clarifies exactly what the evidence does — and does not — prove. • CLINICAL DOCTOR VISIT FILE (PERMANENTLY FREE) Prepare for your endocrinologist or gynecologist visit in seconds. Export a clear, chronological summary of your cycle length distribution, symptom clusters, and confirmed ovulation markers. Always free for every user. • CARE PILLARS Supportive, hormone-friendly daily foundations: - Phase-aware dinner concepts crafted around metabolic ease - Strength movement demos focused on muscle glucose uptake - Calming audio stillness sessions to down-regulate nervous system strain • PRIVACY YOU OWN - No mandatory account creation: explore anonymously with a secure device identifier. - Server-first backup keeps your history safe across phone upgrades. - Optional Sign in with Apple for effortless multi-device recovery. - "Delete everything" purges every record across all server tables instantly and permanently. - Never sold, never shared with data brokers, and never used for advertising.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

- Last period: if you only know the month, you can now say just that. Astraea works from the month and is clear about what it can and cannot read from it. - Earlier periods: a plain way to say you never kept track before this one. - Ask now says which of your cycles were remembered and which were recorded, so every reading names its source. - If your plan is set not to renew, the subscription screen shows the date it ends. - Smaller refinements throughout, including cycle-length lines and details for records carried over from earlier versions.
