POTS and dysautonomia — your personal symptom journal.

Lunaire POTS Tracker is a private, offline symptom diary for people living with postural orthostatic tachycardia syndrome and other forms of dysautonomia. Log how you feel — heart rate, dizziness, fatigue, brain fog, salt and fluid intake, medications — all stored only on your device. No accounts. No cloud. No tracking.

WHAT YOU CAN LOG
• Heart rate readings — sitting, standing, after activity
• Blood pressure readings — sitting and standing
• Dizziness, lightheadedness & near-fainting episodes
• Fainting events
• Fatigue & energy levels
• Brain fog & cognitive symptoms
• Headaches, nausea, tremor, palpitations
• Temperature regulation & sweating
• Salt & fluid intake
• Compression garment use
• Medication and supplement logging — you choose what to track
• Weight, exercise, food & drink
• Free-text notes for anything else that matters

PRIVACY-FIRST BY DESIGN
Your symptom data 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 YOUR OWN PATTERNS
POTS rarely behaves the same two days in a row. Lunaire helps you map your readings against hydration, salt intake, heat exposure, menstrual cycle, sleep quality and medication timing — so you can see what you've recorded over time. Insights, trends and a calendar view make your patterns easy to read.

PDF SUMMARIES FOR YOUR APPOINTMENTS
Generate a clean PDF summary of your logged readings, symptoms and medication notes — useful to share with your doctor in your own words. Months of recorded data beats trying to recall "a bad flare" in a short appointment.

BUILT FOR THE COMMUNITY
POTS is underdiagnosed, under-researched and under-served by generic health apps. Lunaire POTS Tracker is built for this community specifically — with the symptoms, triggers and language that actually matter to people living with dysautonomia and related conditions.
