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, 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.
