PEREGRINE

Your flight record.
Always with you.

A pilot logbook rebuilt from scratch for working airline crew — EASA + FAR compliant, AI dispatcher briefs grounded in real METAR/TAF, and a published fatigue model wired to Apple Health. Built by an active A320 captain.

CURRENTLY IN BETA · iOS · Android dostępny wkrótce

Everything a working pilot actually uses, in one app.

📖

ELECTRONIC LOGBOOK

EASA Part-FCL, FAR Part 61/121/135 and ICAO columns on tap. Import from LogTen Pro CSV or ecrew schedule reports. Rolling-window stats and currency checks built in.

🧭

AI DISPATCHER

Claude-generated briefings with CAT I marginal flagging, alternate viability, jet stream, SIGMETs and NOTAMs. Forbidden to invent weather outside TAF validity.

💤

FITNESS TO FLY

SAFTE three-process model (Hursh 2004) with HRV modulation vs your personal baseline. Effectiveness % + Dawson-Reid equivalent-BAC. Trend indicator, not a dispatch gate.

🌍

CIRCADIAN + LAYOVER

DST-aware body clock via IANA zones, jet-lag recovery countdown, and anchor-sleep vs adapt strategy for short and long layovers. Off-duty periods feed the math.

☢️

RADIATION

Per-flight cosmic-ray dose via CARI-7-simplified model using your actual cruise FL + route. Annual 20 mSv progress bar. Polar-route flag included.

📱

WORKS OFFLINE

Full logbook on-device via Drift/SQLite. Firebase sync only when you have signal. Your data, your phone — no vendor lock-in, export to PDF / CSV whenever.

A line captain frustrated with the existing options.

Existing pilot logbook apps are either bloated with features nobody uses, trapped in a subscription treadmill, or looked designed for the 2010s. As an active A320 captain I needed a tool that opened fast on a phone, imported my ecrew schedule cleanly, and let me brief a sector from gate with real AI-assisted weather analysis.

PEREGRINE is that app. It started as a weekend project after one too many 03:00 briefings done on a laptop, and grew into a full platform covering everything between duty-planning and radiation dosimetry. Every feature comes from something I actually wanted in the cockpit or on layover.

The app is and will remain single-pilot-built. No investors, no growth hacks, no dark patterns. If you find a rough edge, email me.
