What HobbsMD does for you

🔍

Deep Engine Diagnostics

FEVA-Lite EGT oscillation detection, GAMI spread analysis for injected engines, thermal outlier Z-score ranking, and magneto check monitoring — all automated from your JPI data.

📈

AI-Powered Debrief

Powered by Claude, Gemini, or DeepSeek. For each flight, the AI retrieves relevant excerpts from a curated aviation knowledge base — matched to the specific signals in your data — then returns a structured debrief: anomalies, trends, pilot actions, and maintenance flags, each grounded in cited references.

✈

Full Flight History

Every uploaded flight is stored and analyzed in context. The AI tracks developing issues across multiple flight cycles — a rough mag check that keeps appearing, a slowly climbing peak CHT.

✈️

Multi-Aircraft Support

Manage a fleet or share one account for two planes. Each aircraft has its own engine profile, fuel system type (injected or carbureted), and independent flight history.

📱

Mobile-First PWA

Optimized for iPhone and iPad Safari. Install to your home screen for one-tap access on the ramp after each flight. Works offline for previously analyzed flights.

🔓

Your Data, Private

Each account is fully private. Your flight data is never shared across accounts. API keys are stored server-side — never exposed to the browser.
