Tessera PMOS is the first app built around PMOS — the condition formerly known as PCOS, officially renamed in May 2026 to better reflect what it actually is: a multi-system endocrine and metabolic condition that affects 170 million women worldwide. Every tessera tells your story. A tessera is a single tile in a mosaic. Every meal you log, every skin scan, every cycle entry — one tessera. Together, they show the whole picture of your PMOS, and what to actually do about it. WHAT TESSERA DOES • Tessera Score — your daily, evidence-based read on insulin, inflammation, sleep, cycle, and skin. Updates as you log. • Plate Scan — snap your meal, get a PMOS Impact Score with the exact carbs / fat / fiber that matter for your subtype. • Face Scan — weekly skin progress over time, scored on inflammation, acne, and hormonal markers. • Cycle tracking — phase-aware insights, warm period messages, ovulation window. • Maya, your AI coach — trained on functional medicine, talks like a knowledgeable older sister, never preachy. • Apple Health, deep — cycle, sleep, HRV, resting HR, weight, BBT, VO₂ max, walking HR, respiratory rate, and more. • Widgets + Watch — your score and today's action, with a wilting-leaf mood that gently nudges when you skip meals or water. • Doctor Brief — one tap exports a clinician-ready PDF of your last 30 days. PRIVACY FIRST Your photos never leave your device unencrypted. Plate scans are sent transiently to our AI provider, never stored, never used for training. Cycle and reproductive data is encrypted at rest and never shared with third parties under any circumstance. ABOUT THE PMOS NAME CHANGE In May 2026, a global consensus of 56 medical organizations — including The Lancet, the Endocrine Society, and Monash University — officially renamed PCOS to PMOS (polyendocrine metabolic ovarian syndrome). The new name finally reflects what the condition truly is. Tessera uses PMOS. Both terms will be in use for a 3-year transition period. SUBSCRIPTION 7-day free trial, then $9.99/month or $59.99/year. Cancel anytime in iOS Settings. Tessera PMOS is a lifestyle and tracking app. It does not diagnose, treat, or cure any condition. Maya is an AI assistant, not a medical professional. Always talk to your doctor. Terms of Use (EULA): https://tesserapmos.com/terms Privacy Policy: https://tesserapmos.com/privacy
