Nosce

Nosce te Ipsum — know thyself. Track your cycle, skin, hair, medications and movement — privately, and without being told your period is "late." QUIET BY DEFAULT Most cycle trackers predict your next period and count days as late, which falls apart the moment your cycle isn't textbook regular — PMOS (formerly PCOS), perimenopause, or birth control all make "late" meaningless. Nosce tracks without predicting unless you turn forecasts on, and even then shows a range, never a single date. It never suggests a pregnancy test. PRIVATE BY ARCHITECTURE, NOT POLICY No account. No sign-in. No servers. No analytics. No ads. Nosce makes zero network requests — everything you log stays on your device, full stop. Not "we don't sell your data." We can't see it at all. BUILT FOR SEVEN LIFE STAGES, NOT JUST "THE CYCLE" Set your mode — cycling, birth control, trying to conceive, pregnant, postpartum, perimenopause, or post-menopause — and Nosce tracks and stays quiet about exactly what applies. The exercise library carries evidence-informed guidance across PMOS (formerly PCOS), perimenopause, endometriosis, period pain, postpartum, and PMS/PMDD. TALK TO YOUR DOCTOR WITH DATA, NOT A NOTES APP Export a paginated Doctor Report — burden-ranked symptoms, cycle statistics, and a medication timeline with adherence — sized for a twelve-minute appointment. Raw CSV export is always free, because anti-lock-in is a trust signal, not a premium feature. SEE YOUR OWN PATTERNS Nosce's correlation engine finds real patterns in your own data — symptom timing relative to your period, medication before/after comparisons, how movement affects how you feel — and labels findings preliminary below a data threshold. Correlation is never called cause. MORE THAN LOGGING - Photo timeline for skin and hair, with before/after comparison - Medication tracking with dose, schedule, and adherence - Movement logging with a post-session "how did it leave you feeling" check - Import from Clue, CSV, or Apple Health (read-only — Nosce never writes back) - Encrypted, on-device backup protected by a passphrase only you know - Face ID lock for the whole app Free, with every feature included. No paywall, because paywalls on health data are part of the problem. Nosce is a private tracking tool, not a medical device. It does not diagnose and does not offer contraceptive-grade fertility prediction.
