Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

1-tap migraine logging. Auto barometric pressure. 100% offline. No account. No subscription. Built for light sensitivity. When light is the enemy, every tap counts. Dark Logger is a precision migraine and headache tracking tool engineered for users with photophobia and severe light sensitivity. Built on a deep charcoal interface with muted, low-saturation colors — because the app should never add to the pain. Log what matters in seconds Severe symptoms demand zero friction. Dark Logger's 1-tap quick log captures a timestamped entry the moment you need it — no account creation, no onboarding, no unnecessary navigation. Log pain intensity, medications, notes, and triggers without unlocking a dozen menus. Built for the moment of pain · Deep charcoal UI — no bright whites, no harsh surfaces · Low-saturation, muted palette engineered for visual strain · Large tap targets and minimal screen hierarchy · No animations, no popups, no distractions during an episode Weather & barometric pressure — automatic Barometric pressure drops are a documented migraine trigger. Dark Logger automatically logs local weather conditions and pressure readings alongside every entry — no manual input required. Correlate your patterns without extra work. Fully offline. Fully private. Your health data lives entirely on your device. Dark Logger has no cloud sync, no user accounts, no analytics, no third-party SDKs, and no social features. Nothing leaves your phone. Nothing is tracked. Nothing is sold. Export-ready for your doctor 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.
