Sana: PCOS & Period Tracker

Sana is a PCOS-focused cycle and symptom tracker that works fully offline — not a generic period app with a PCOS label stuck on, and not an account you're forced to create before you can even start logging. THE PROBLEM WITH OTHER PERIOD TRACKERS Most period and cycle tracking apps assume a 28-day cycle. If you have PCOS, your cycle might run anywhere from 25 to 90 days — so those apps get it wrong most of the time, and some don't even let you log a PCOS diagnosis in the first place. WHAT MAKES SANA DIFFERENT - Real cycle ranges, not fake precision. Sana shows an honest range (like "Day 18-34") built from your own logged cycles — never a confident-sounding wrong date. - Built to work offline. Log your period, symptoms, and mood with no internet connection — your data lives on your device first. - PCOS symptoms that actually matter. Acne, excess hair growth, hair thinning, sugar cravings, fatigue, mood, and more — logged in seconds. - Doctor-ready reports. Export a clean PDF summary of your cycle history, symptoms, and patterns to bring straight to your OB-GYN or endocrinologist appointment. - Pattern detection. Once you've logged a few cycles, Sana surfaces real patterns — like which symptoms tend to show up before your period starts. - A real free tier. Core cycle tracking, symptom logging, and insights are free — not a trial that quietly expires. - Privacy first. Your data is encrypted, never sold, and you can export or permanently delete it anytime from Settings. FEATURES - Home dashboard with your personalized cycle range - One-tap daily symptom logging - Insights that show your real cycle history and detected patterns - Doctor report export (PDF) for your next appointment - A supportive, anonymized community to ask questions and share what's working - Works offline — syncs automatically once you're back online Sana doesn't replace your doctor — medical content is reviewed by an OB-GYN, and we'll always tell you when something's worth bringing to an appointment. Built for the roughly 1 in 10 women living with PCOS, PCOD, or irregular cycles who deserve a period and symptom tracker that actually understands their cycle — not a generic calendar app guessing at 28 days.
