Took your levothyroxine? Thyroid Coach starts the wait window and tells you the moment breakfast and coffee are a go. Iron reminders stay 4+ hours away from your thyroid pill, with a gentle heads-up if they drift too close. No account. No cloud. Everything stays on your iPhone. YOUR MORNING, HANDLED • One tap logs your dose and starts a live countdown. • The countdown runs on your Lock Screen and in the Dynamic Island, so you never unlock the phone to check. • A Home Screen widget shows what's next and which of today's steps are done. • A "breakfast is a go" notification when the wait is over, even with the app closed. • Log it straight from the reminder on your Lock Screen, half awake. • Running late? Record the time you actually took it. IRON WITHOUT THE GUESSWORK • Iron reminders placed well away from your thyroid medication. • A friendly warning if you log them too close together, never a block. • Alternate-day iron supported, with rest days shown for you. A 30-SECOND CHECK-IN • Energy, mood, clarity, sleep and the symptoms that matter with thyroid and iron. • No streaks, no guilt. Missed days are information, not failures. TRENDS THAT MAKE SENSE • 7, 30 and 90 days of how you have actually felt. • Your medication routine in plain language, never a report card. YOUR LABS, IN ONE PLACE • TSH, Free T4, Free T3, TPO antibodies, ferritin, hemoglobin, transferrin saturation, vitamin D and B12. • Plan your next blood draw and get a reminder that morning with the prep to remember. • No flags, no interpretation. Your doctor reads your results; the app just keeps them tidy. A REPORT FOR YOUR DOCTOR • One tap turns your logs into a clean summary of routine, symptoms and lab history, with questions worth asking. • Share it as a PDF or as text before the appointment, or read it from your phone in the room. LEARN, WITH THE SOURCES • Short cards on absorption, the iron and thyroid connection, supplements, myths and what recovery really looks like. • Every card is graded by how strong the evidence is and links to where it came from. PRIVATE BY DESIGN Everything you enter stays on your iPhone. There is no account and no server: your doses, check-ins, notes and lab results are never uploaded. The app collects anonymous usage statistics so it can be improved — never your health data, and you can switch it off in Settings. NOT MEDICAL ADVICE Thyroid Coach is a personal logging and reminder tool, not a medical device. It never suggests doses and never interprets lab results. Always follow your prescriber's instructions and talk to your doctor before changing anything about your treatment. SUBSCRIPTION Thyroid Coach Pro unlocks the full app: $3.99 per week or $79.99 per year, each starting with a 3-day free trial. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of the period. Manage or cancel in your Apple Account settings.
