You know something is changing. Your doctor visits are 15 minutes. AsterLuna helps you walk in with proof. AsterLuna is a private perimenopause symptom tracker built around one idea: your experience is real, and it deserves to be taken seriously. Log your day in under 30 seconds, watch your patterns emerge, and generate a clear PDF report to bring to your appointment. It goes far deeper than a cycle app: built only for this transition. TRACK WHAT IS ACTUALLY HAPPENING • 34 built-in symptoms, from hot flashes and night sweats to brain fog, joint pain, mood, cravings, and the ones nobody warned you about • Add your own custom symptoms • One-tap logging for countable symptoms like hot flashes, with automatic timestamps • Cycle tracking built for perimenopause, where irregularity is the signal, not a bug • A private journal: notes for your next appointment, as personal or as brief as you want SEE YOUR PATTERNS • Trends for every symptom across 30, 90, or 365 days • Cycle overlay to see how symptoms move with your cycle • A dedicated Mood & Mind view, because your mental health matters most of all BRING YOUR DOCTOR PROOF • Generate a clean, printable PDF summary of your symptoms, cycle, and severity over time • You choose exactly what goes in it, including which journal entries, if any • Your first report is free PRIVATE BY DESIGN • No account. No sign-up. No tracking. • Your health data lives on your device and in your own private iCloud. We have no server that collects it. We cannot see it, and we cannot sell it. • Export your data anytime as a CSV, free, forever. It is yours. FEEL LESS ALONE • The Circle: send and receive anonymous notes of encouragement from other women in this transition. No profiles, no comments, no free text. Just "you're not alone," and it is always optional. • Gentle companion notes with real prevalence facts, because half the battle is learning that what you are feeling is common. A CALM PLACE TO LAND • A soft, botanical design with original artwork, built to be readable on the hardest days • A discreet home screen widget that shows your day's log count, and nothing else • Daily reminders that never name a symptom in a notification FREE AND PAID Logging, journaling, cycle tracking, and CSV export are free forever. Your first doctor report is free too. Trends and unlimited reports unlock with AsterLuna Pro: a one-time lifetime purchase if you want to keep your history forever, or a monthly subscription with a 7-day free trial if you are just passing through this season. AsterLuna is a personal tracking tool. It does not diagnose or treat any condition and is not a substitute for professional medical care. Always talk with a qualified provider about your health.
