Thyroid Symptom Tracker

Thyroid symptom, TSH & medication tracker. Private. Offline. Your device only.

Thyroid symptoms and medication, tracked on your terms.

Lunaire Thyroid Tracker is a private, offline symptom 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.

PRIVACY-FIRST BY DESIGN
Thyroid data — lab results, medication history, symptom patterns — is deeply personal. It doesn't belong on someone else's server.
✓ 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 helps you map 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. Insights, trends and a calendar view make the pattern unmistakable.

PDF REPORTS FOR YOUR GP OR ENDOCRINOLOGIST
Generate a clean PDF summary of your symptoms, TSH/T3/T4 history and medication timeline — share it with your GP 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, NOT MARKETERS
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.
