Fingers turning white, then blue, as the days get colder?
Log each attack in seconds - the weather is added for you.
Show your doctor a clear PDF. No account needed.
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 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 the average severity of your attacks over the last 7 days and your most common triggers over the last 30 days. Watch the patterns emerge as your log grows.
WINTER IS THE HARD SEASON
Many people with Raynaud's notice more attacks once the temperature drops. VasoLog helps you 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
Your attack records are stored only on your device. No cloud sync and no account needed. 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.

IMPORTANT: VasoLog is a personal symptom diary, not a medical device. It does not diagnose, treat, cure, or prevent any condition. VasoLog is meant to support professional care, not replace it - always check with a qualified healthcare professional for medical advice, diagnosis, or treatment, and before making any decisions about your health.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
VasoLog now follows the system Reduce Motion setting. Turn it on in Settings > Accessibility > Motion, and screens appear in place instead of sliding in, charts fill without animation and the record button stops bouncing. The app does exactly the same things, just more calmly.
Also in this update:
• The daily reminder no longer arrives on a day when you have already logged an attack or answered how your hands are
• Google Firebase has been removed from the app completely - crash diagnostics now go through a single service
• The weather service receives your location rounded to about a kilometer instead of your exact coordinates
• The privacy policy inside the app has been rewritten and now explains how your subscription is verified
• The entry form no longer opens a second time after you change the language
Requires iOS 15 or later.
