Dark Logger: Migraine Tracker

A photophobia-safe, 100% offline migraine and headache tracker. Zero accounts.

Built for the reality of severe migraines. When an attack hits, staring at a bright white loading screen or navigating five complicated menus is pure torture. You need to log your symptoms and put your phone away.
Dark Logger is a strictly offline, photophobia-friendly migraine diary designed specifically for high cognitive load and extreme light sensitivity.
No accounts to create. No cloud syncing. No bloatware. Just a fast, soothing interface that respects your eyes and your privacy.
### KEY FEATURES:
🕶️ ULTRA-LOW CONTRAST UI
True dark mode with muted colors. Designed to minimize visual strain and avoid triggering photophobia during an active aura.
🔒 100% OFFLINE & PRIVATE
Your medical data is nobody's business. There is no cloud, no tracking, and no data collection. Everything stays strictly on your device's local storage.
⚡ 1-TAP QUICK LOGGING
When the pain starts, just tap the main button to instantly timestamp the attack. You can fill in the pain scale, symptoms, and triggers hours later when you feel better.
📄 EASY DATA EXPORTS
Stop handing over messy handwritten notes. Dark Logger automatically generates clean 30-day and 90-day PDF summaries, highlighting total episodes, average pain, and top symptoms to help you spot trends instantly.
⛈️ WEATHER & PRESSURE TRACKING
Automatically log the barometric pressure and weather conditions at the exact moment of your attack to see if environmental drops are your hidden trigger.
### DESIGNED WITH EMPATHY
When dealing with severe photophobia, the last thing you want to do is navigate bright screens and complex menus. I couldn't find a tracker that was purely dark, completely offline, and fast enough to use during an attack—so I built one. Dark Logger is a passion project designed to make logging as frictionless as possible.
