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.
