Thyroid Symptom Tracker

Living with thyroid disease means being told your labs look "normal" while you can't get out of bed, gaining or losing weight you can't explain, and trying brands and doses for months to find what actually works. Lunaire Thyroid Tracker is a private, offline symptom and medication diary built for people living with hypothyroidism, hyperthyroidism, Hashimoto's and Graves' disease. Log fatigue, weight changes, mood, TSH results, levothyroxine doses and side effects — all stored only on your device. No accounts. No cloud. No tracking.

WHAT YOU CAN TRACK
• Fatigue & energy levels
• Weight changes — gain, loss, fluid retention
• Body temperature & cold/heat intolerance
• Hair loss, dry skin, brittle nails
• Mood — low mood, anxiety, irritability
• Brain fog & concentration issues
• Heart rate & palpitations
• Sleep quality & insomnia
• Bowel habits — constipation, loose stools
• Menstrual cycle changes
• Joint aches, muscle weakness, tremor
• TSH, T3, T4 and antibody results (TPO, TgAb, TRAb)
• Medication adherence — levothyroxine, liothyronine, NDT, carbimazole, methimazole
• Supplements — anything you take
• Weight, Temp, exercise, food & drink

PRIVACY-FIRST BY DESIGN
Thyroid data — lab results, medication history, symptom patterns — is deeply personal.
✓ Everything stays on your device
✓ No account, no sign-up, no email
✓ No cloud sync, no analytics, no ads
✓ Works fully offline
✓ You own the data — back it up or delete it in one tap

SEE WHAT YOUR LABS AREN'T TELLING YOU
"Your TSH is in range" rarely tells the full story. Lunaire maps your symptoms against lab results, dose changes and brand switches over weeks and months — so you can see whether you feel better on 100mcg versus 125mcg, whether switching brands flared your symptoms, and how your energy tracks with T3 levels. A calendar view and symptom-vs-lab timeline come as standard; deeper 90-day trend analysis is part of Premium.

PDF REPORTS FOR YOUR DOCTOR
Generate a clean PDF summary of your symptoms, TSH/T3/T4 history and medication timeline — share it with your doctor or endocrinologist in one tap. Months of tracked data is worth more than "I've just been really tired" in a ten-minute appointment.

BUILT FOR THYROID PATIENTS
Thyroid patients are often told they're "fine" when they clearly aren't. Lunaire Thyroid Tracker is built for this community specifically — hypothyroid, hyperthyroid, Hashimoto's, Graves', post-thyroidectomy, RAI — with the symptoms, labs and language that actually matter.
