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

PDF REPORTS (PREMIUM)
