Always with you.

A pilot logbook rebuilt from scratch for working airline crew. EASA & FAR compliant, with live METAR / TAF / NOTAM briefings, a moving map with radar and SIGMETs, EASA FTL + FAR Part 117 duty monitoring, currency tracking, and a SAFTE fatigue model wired to Apple Health. Built by an active A320 captain.

BUILT-IN

Everything a working pilot actually uses, in one app.

📖

ELECTRONIC LOGBOOK

EASA Part-FCL, FAR Part 61/91/121/135 and ICAO column views on tap. Import from LogTen Pro, ForeFlight, SafeLog and MyFlightBook CSV, or Apple Calendar. Aircraft database with per-tail flags that cascade into history.

🌦

WX BRIEFING & MAP

Live METAR / TAF / NOTAM per airport with ICAO Q-code decoding, severity colouring, and an ACTIVE pill on NOTAMs that bite during your flight window. Moving map with RainViewer radar and SIGMET polygons.

🛂

FDP & DUTY MONITORING

EASA FTL + FAR Part 117 envelope. Planned vs max FDP, latest-legal departure margin per sector, in-flight rest limits and cumulative-delay rollup — no mental arithmetic at the gate.

💤

FITNESS TO FLY

A SAFTE fatigue model (Hursh 2004), HRV-adjusted against your personal baseline. Effectiveness % and Dawson-Reid BAC equivalence — a trend read, never a dispatch gate.

🌍

CIRCADIAN

A DST-aware body clock via IANA zones, jet-lag severity detection, and off-duty logging that feeds post-vacation reacclimation. It tells you where your clock is — it doesn't prescribe what to do about it.

CURRENCY & DOCS

FAR Part 61 90-day landing recency, instrument approach + IPC tracking, and a document-expiry monitor for licences, medicals and recurrent checks. Expiring-docs banner surfaces 30 days out.

📤

AUDIT-READY EXPORTS

EASA Part-FCL.050 PDF (LogTen-style A4 landscape spread), Jeppesen Pro PDF, and full-fidelity CSV. A pre-export validator flags missing mandatory columns and jumps you to the row to fix before audit.

📱

OFFLINE FIRST

The full logbook lives on-device in SQLite. WX + NOTAM cache survives airplane-mode flights. Firebase sync runs only when you have signal — your data, your phone, no vendor lock-in.

ON THE BIG SCREEN

Your logbook, on the web.

Sign in on any desktop or tablet to browse and edit the flights you log on your phone — EASA & Jeppesen column views, duty grouping, stats, CSV / PDF export, light & dark themes. Read-write and synced live with the app.

Open web logbook

Requires a Peregrine account created in the app.

WHO BUILT THIS

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 look designed for the 2010s. As an active A320 captain I needed a tool that opened fast on a phone, imported my schedule cleanly, and let me brief a sector from the gate with live METAR / TAF / NOTAM coverage.

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 gate briefing, duty planning and currency. 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.
