Raynaud's Phenomenon

An attack diary for Raynaud's — Raynaud's phenomenon (RP), Raynaud's disease (primary), or Raynaud's syndrome (secondary, alongside conditions like scleroderma or lupus); the digital vasospasm behind white, cold, numb fingers and toes.

Log an attack the way it happened:
• Zones grouped naturally — face, hands, feet — with left/right fingers and toes
• Color changes (white, blue, red) with a "didn't notice" option
• Attack duration and rewarming time as one-tap bands (no typing with numb fingers)
• Attack severity, numbness, and loss of hand/foot function
• What you tried and whether it helped, plus outdoor temperature captured automatically when you allow location
• Photos, triggers (cold, stress, caffeine and more), medications, and notes

Insights derive attacks-per-week from your entries automatically — no need to estimate — and chart severity, duration and temperature correlation over time. PDF reports and CSV export support rheumatology visits.

Log from your wrist: an Apple Watch companion app is included for quick one-tap entries that sync to your phone.

Your data stays on your device — no account, no sign-up, and your health information is never uploaded to our servers. Export everything anytime as CSV or a PDF report.
