Dark Logger: Migraine Tracker
Headache Diary · True Dark
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A migraine tracker you can use during a migraine. Dark screen, one-tap logging, 100% offline, no subscription. Auto barometric pressure logging.
When a migraine hits, your phone becomes an enemy. Bright interfaces. Multi-step menus. 12 taps to log one symptom.
Dark Logger was built for that exact moment. One tap starts the clock. You log the details when the pain passes.
BUILT FOR PHOTOPHOBIA
The UI stays dark — deep charcoal, no flash, no white screens, no blue light. Every touch target is oversized. There's nothing to read during an attack.
AUTO-CAPTURES CONTEXT
Logs barometric pressure at the exact moment of every attack. No manual input. Tracks medications with effectiveness ratings. Daily sleep and stress check-ins help surface patterns. After 7 logged attacks, the daily risk score activates.
REPORTS FOR YOUR NEUROLOGIST
Generate clean 30-day or 90-day PDF reports formatted for clinical review. Bring structured, timestamped data to your neurologist or headache specialist — not a screenshot.
WHAT DARK LOGGER IS NOT
· Not a subscription service
· Not a cloud-connected database
· Not a bloated wellness app with a step counter
· Not a social platform
Dark Logger is a focused, high-performance utility for one job: helping you track, understand, and communicate your migraine patterns — without the app making things worse.
100% offline. No account. No sign-up. Your medical data never leaves your device.
