VasoLog: Raynaud's Tracker

Cold hands, fingertips turning white then blue, numbness and a deep ache - a Raynaud's attack can take over your day in seconds. VasoLog is the symptom diary built for exactly this.

Track what happens, spot what sets it off, and turn months of scattered episodes into one clear picture you can actually show your doctor.

TRACK EVERY ATTACK
Log each episode in seconds: which fingers or toes are affected, the color phase (white to blue to red), severity on a 0-10 scale, and how long it lasted. Attach a photo and add notes for a complete record.

WEATHER, CAPTURED AUTOMATICALLY
Every episode is paired with the weather at your location - temperature, humidity, atmospheric pressure, and wind. No manual entry. See how cold snaps and pressure swings lined up with your past episodes.

KNOW YOUR TRIGGERS
Tag the usual suspects - cold exposure, stress, vibration, smoking, caffeine, and more. Over time, VasoLog lines up your episodes with the triggers you tagged, so the patterns are easy to spot.

CHARTS THAT MAKE SENSE
Your dashboard shows attack frequency over the last 7 days and a monthly trigger breakdown. Watch the patterns emerge and see how the seasons correlate with your episodes.

WINTER IS THE HARD SEASON
Many people with Raynaud's notice more attacks once the temperature drops. VasoLog helps you compare this winter to the last and bring a clear record - notes, weather context, and your logged episodes - to your next appointment.

ONE-TAP REPORT FOR YOUR DOCTOR
Generate a clean PDF for any date range and share it with your rheumatologist, vascular specialist, or GP. Walk into your appointment with real data instead of trying to recall every episode from memory.

YOUR DATA STAYS YOURS
Everything is stored locally on your device. No cloud, no account, no third-party tracking. Your health information belongs to you and no one else.

BUILT FOR PEOPLE WITH RAYNAUD'S
Whether you were just diagnosed or have managed Raynaud's for years, VasoLog helps you log, understand, and communicate your episodes. A steady, organized record gives your care team the full picture - so every appointment starts with facts instead of guesswork.
