Your flight bag, organised.
Documents, logbook, and the everyday flight-deck tools line pilots actually reach for — together in one clean, fast app.
AerologHQ is a small studio building honest, no-nonsense apps and guides. Made on the line by a working airline captain, refined by the people who use them every trip.
Built and maintained by a current A350 line captain
Three are built for flight crew. Four — Keepr, Pantri, 4Cast Weather, and ImageLocate — are for everyone, whether or not you fly.
Your flight bag, organised.
Documents, logbook, and the everyday flight-deck tools line pilots actually reach for — together in one clean, fast app.
Your roster, made clear.
Track duties, flights, and schedule changes at a glance. A calm, reliable companion for crew who live by the roster.
Every trip, briefed.
A focused pre-flight briefing companion that pulls the trip together — weather, route, and prep — so you walk to the aircraft ready.
Never miss a return window again.
Track return deadlines and warranties before they cost you. A beautiful countdown between a purchase and money quietly lost. For everyone, not just pilots.
Cook what you have. Waste less.
Track what's in your fridge and pantry, get a warning before food expires, and turn the ingredients you already have into recipes — generated privately, on your device.
More than a temperature.
Hyperlocal forecasts, minute-by-minute rain timing, and an interactive radar, under a live sky that reflects the one outside. One purchase — no subscriptions, no ads, no tracking.
Where was this photo taken?
Works out where a photo was taken — even which floor — when there's no GPS to go on, and shows its working. Analysis happens on your device. One purchase, no subscriptions.
Our flagship written guide — an honest framework for the DEC assessment. No leaked question banks, no hype. Just the structure that gets a working captain through.
A 42-page working pack plus five companion templates and three live spreadsheets. Print them, fill them in, adapt them to your situation — from the first self-assessment to your first year in command.
42-page PDF + 5 companion templates + 3 working spreadsheets.

Everything here is built by someone who still flies for a living — and shipped only when it's genuinely useful.
An active A350 line captain designs and maintains these tools around real rosters, real trips, and real flight-deck constraints.
No hype, no dark patterns, no selling secrets that shouldn't be sold. If something isn't ready or isn't useful, it doesn't ship.
Your data stays yours. The apps favour on-device processing and work when the network doesn't.
A current line captain on the A350. The apps and the pack are published under AerologHQ; direct contact is available for substantive questions.
Most are free to download, and several offer a free tier with an optional upgrade. 4Cast Weather and ImageLocate are one-time purchases with no subscriptions. Tap through to the App Store or Google Play for current pricing.
No. Aerolog EFB, Flyers, and PreBrief are built for flight crew. Keepr, Pantri, 4Cast Weather, and ImageLocate are for everyone, whether or not you fly.
No. The pack is explicit about this on page one. It's an airline-agnostic framework — sim technique, interview themes, and the decision to accept or decline — not leaked questions.
App updates ship through the stores. The DEC pack is a one-time purchase with future updates included and a 7-day refund handled through Gumroad.
