A beautifully crafted, completely private tracker for Thyroid conditions. Log lab results, fatigue, brain fog, hair loss, symptoms, weight, blood pressure, supplements, food and exercise, plus your own personal daily journal.
Clean, Calm and Completely Private.
Fatigue, brain fog, hair loss, weight changes, cold intolerance — 40 symptoms across 8 categories, every one ready to log on day one on a simple five-point scale.
Track your daily supplements, with reminders you can snooze or mark as taken straight from the notification — no need to even open the app.
Watch symptoms rise and fall on clear, beautiful charts — and spot the food and supplement patterns behind your better weeks.
Log meals with tags built for thyroid health — gluten, soy, goitrogens, selenium-rich and more — and save favourite meals to log again in a tap.
Log weight in kg, lbs or st with visual trend charts. Useful for following thyroid-related weight changes.
Track activity type and intensity from a built-in catalogue, or add your own exercises with Premium.
Log your temperature in °C or °F, timestamped. Spot changes that may relate to thyroid function.
Record TSH, free T3, free T4, TPO antibodies and ferritin, dated, and read them alongside your symptoms — your bloods and how you actually felt, finally on one timeline. Units follow your region, SI or US.
Log a reading — systolic, diastolic and pulse — and follow all three on one chart.
Keep every appointment in one place, with notes. Add reminders and a PDF report to take along with Premium.
Turn months of logs into a clean, doctor-ready PDF — symptoms, lab results, food and supplements — ready to share at appointments.
Add your own symptoms and exercises alongside the built-in catalogue, so the app tracks your condition — not a generic one.
Choose which shortcuts appear on Home, drag them into your own order, colour them your way — and put your name at the top.
Set backups to run themselves, on a schedule you choose. Manual backup and restore stays free for everyone.
All data lives on your device — no cloud, no accounts, no tracking — with a biometric app lock for good measure.
Thyroid symptoms are famously vague one at a time and famously obvious as a pattern. Lunaire Thyroid Tracker ships with 40 symptoms across 8 categories, ready to log on day one. With Premium, you can hide the ones that don't apply and add your own symptoms or exercises to track what really matters to you.
Morning tiredness and an afternoon crash are different problems with different shapes across a week. They're logged separately rather than as one energy score.
Thyroid symptoms are routinely mistaken for anxiety or low mood. Logging them alongside the physical entries is what shows the two moving together.
Cold and heat intolerance are both here, because thyroid symptoms don't all run in the same direction. Weight can be logged with its own trend chart alongside these.
Eyebrow thinning and brittle nails are the sort of slow change nobody notices until it's well established. Dated entries give you the timeline.
Gut symptoms move with thyroid function more than most people expect, and they sit alongside the food diary so both are recorded together.
Neck and throat discomfort has its own entry, as does tingling in the hands — both easy to mention in passing and forget by the next appointment.
Cycle changes and fertility concerns are tracked here rather than being split off into a separate app. Entries that don't apply to you can be hidden.
A hoarse voice or facial puffiness is the kind of thing other people notice first. Logging it yourself means it's on the record with a date attached.
Tag what you ate and it sits next to the symptoms you logged that day, so you can look back at both together rather than reconstructing it from memory.
Every symptom and exercise is rated on a simple five-point scale.
You can log the same symptom or exercise multiple times a day.
The above screenshots are just a small selection from the app.
All screenshots show example data, not real records.
Your symptom data is deeply personal. Lunaire Thyroid Tracker is designed from the ground up so your information never leaves your device. No sign-ups, no adverts, no analytics — just a beautiful app that respects you, your body and your data.
