Thyroid Tracker & Diary

Being told your labs look "normal" while you can't get out of bed is exhausting. Lunaire Thyroid Tracker & Diary is a private, offline symptom and lab diary for hypothyroidism, hyperthyroidism, Hashimoto's and Graves' disease.

WHAT YOU CAN TRACK • Fatigue, morning tiredness and energy crashes • Weight gain, difficulty losing weight, fluid retention • Body temperature, cold and heat intolerance • Hair loss, dry skin, brittle nails • Mood — low mood, anxiety, irritability • Brain fog, concentration, memory and heart rate changes • Sleep quality • Digestion — constipation, bloating, reflux, nausea • Menstrual cycle changes • Joint pain, muscle aches, tingling hands • Lab results — TSH, FT3, FT4, TPO antibodies and ferritin • 40 built-in symptoms in total • Supplements, food, drink and exercise • Weight (kg, lbs or st), blood pressure, pulse and temperature • Appointments and daily notes (reminders with Premium)

Every symptom and exercise is rated on a simple five-point scale — you can log the same symptom or exercise multiple times a day. Many people live with more than one condition, so with Premium you can add symptoms of your own and hide the ones you don't use — the lists end up matching you.

PRIVACY-FIRST BY DESIGN • No accounts. No sign-up. Open the app and start logging. • No tracking. Your data lives in a local database only you control. • No ads. Ever. No analytics. • Works fully offline.

PDF REPORTS (PREMIUM) Generate a clean PDF of your symptoms and TSH, FT3 and FT4 history — share it with your doctor or endocrinologist in one tap.
