Why Canairy?

✓ Hyper-local Precision

Canairy uses exact GPS coordinates (Address-Level) to pull data specific to the user's immediate elevation and micro-climate.

✓ Research-Backed

Canairy uses a scientifically calibrated baseline (8.0 hPa) derived from clinical studies (e.g., Okuma et al.), ensuring that the critical "danger zone" of 6–10 hPa always registers as a high-probability risk.

✓ The "Stabilization Protocol"

Canairy offers a Bio-Hacking Checklist specific to barometric pressure physiology. It recommends targeted interventions like Vasoconstriction (Caffeine/Ice) and Vestibular Regulation (Earplugs) to directly counteract the physical mechanism of the trigger.

✓ Privacy-First Architecture

Canairy is Zero-Login. All data and logic live locally on the device (UserDefaults), respecting the user's privacy and ensuring the app works instantly without a server connection.

Why weather causes migraines…

Rapid barometric pressure drops create a differential where external pressure falls faster than your body can equalize. This forces cranial blood vessels to expand (vasodilation) and inner ear pockets to swell, irritating the sensitive trigeminal nerve. This physical expansion is the primary migraine trigger, especially during drops of 6–10 hPa, which clinical studies identify as a critical threshold where neural hyperexcitability and pain frequency spike significantly.

The Hyper-local tech

While most apps rely on distant airport data (METAR), Canairy uses a hyperlocal interpolation engine. It queries meteorological grid models using your exact GPS coordinates, automatically accounting for your specific elevation and micro-climate. This method detects the precise pressure slopes (deltas) at your physical location, capturing the steep drops that trigger symptoms but are often smoothed out by broad, city-wide forecasts.
