Osmi is a cycle tracker and food scanner for women with Hashimoto's and other thyroid conditions. Your cycle, what you eat and how you feel, read together in one app. YOUR CYCLE AS ONE RING Log a period in a tap, or tell Osmi when your last one started and ended. Your whole cycle sits on one ring: period days shaded by how heavy the flow was, your fertile days and ovulation marked as estimates. Drag the day marker to read any day. Already logging in Apple Health? Connect it and your past periods come in. SCAN WHAT YOU EAT Scan a barcode or photograph the ingredient list. Osmi marks each ingredient Fine, Watch or Avoid and says why in plain words: added sugar, seed oils, the additives we flag. It points out what's worth knowing if you live with a thyroid condition, and every product you scan stays in your library. HOW YOU FEEL, EVERY DAY Seven short questions a day: energy, brain fog, feeling cold and more. What you ate and how you moved sit on the same page. Your sleep and heart rate from Apple Health sit beside them, compared with your own recent usual, not a population average. WALK IN PREPARED You see your doctor for about fourteen minutes a year. Osmi keeps the record in between and turns it into a short summary for your appointment: your latest results, what you noticed, and what you changed since last time. YOUR LAB RESULTS (BETA) Photograph a lab report. Osmi reads each result and shows it against the range your own lab printed. Never "normal", never a grade we invented. PRIVATE BY DESIGN No account to make. Your period records, symptoms, lab values and Apple Health data are never sent to analytics or advertising tools. WHAT OSMI WILL NOT DO Osmi is educational, not medical advice. It never diagnoses, never tells you what dose to take, and never claims one thing caused another. Ovulation and fertile days are estimates from your dates, not birth control. Osmi can suggest asking your doctor. It will never talk you out of it.
