Lupus Flare Tracker

Living with lupus means never knowing when the next flare will hit, and explaining an invisible illness to people who think you look fine. Lunaire Lupus Tracker is a private, offline flare and symptom diary. Everything you log stays on your phone.

WHAT YOU CAN TRACK
• Lupus flare severity, UV exposure and suspected triggers
• Joint pain location and intensity
• Malar (butterfly) rash, discoid rash and skin changes
• Fatigue and energy levels
• Mouth and nose ulcers, hair loss, Raynaud's episodes
• Brain fog and cognitive symptoms
• Fever and sun sensitivity
• 42 built-in symptoms in total, plus food, mood and sleep
• Exercise by type and intensity, and supplements
• 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.
