Thyroid Symptom Tracker

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

WHAT YOU CAN TRACK
• Fatigue and energy levels
• Weight changes — gain, loss, fluid retention
• Body temperature, cold and heat intolerance
• Hair loss, dry skin, brittle nails
• Mood — low mood, anxiety, irritability
• Brain fog, concentration, heart rate and palpitations
• Sleep quality and insomnia
• Bowel habits — constipation, loose stools
• Menstrual cycle changes
• Joint aches, muscle weakness, tremor
• 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, with reminders

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 you can add symptoms of your own and hide the ones you don't use — the lists end up matching you.
