The apps

Seven apps, one standard: useful, honest, quietly good.

Three are built for flight crew. Four — Keepr, Pantri, 4Cast Weather, and ImageLocate — are for everyone, whether or not you fly.

Aerolog EFB app icon
Aerolog EFB Electronic Flight Bag

Your flight bag, organised.

Documents, logbook, and the everyday flight-deck tools line pilots actually reach for — together in one clean, fast app.

Flyers crew roster app icon
Flyers Crew Roster

Your roster, made clear.

Track duties, flights, and schedule changes at a glance. A calm, reliable companion for crew who live by the roster.

PreBrief app icon
PreBrief Pre-flight Briefing

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.

Keepr app icon
Keepr Returns & Warranty

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.

Pantri app icon
Pantri Food & Recipe Rescue

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.

4Cast Weather app icon
4Cast Weather

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.

ImageLocate app icon
ImageLocate Photo Geolocator

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.

Why AerologHQ

Made on the line, not in a boardroom.

Everything here is built by someone who still flies for a living — and shipped only when it's genuinely useful.

01

Built by a working captain

An active A350 line captain designs and maintains these tools around real rosters, real trips, and real flight-deck constraints.

02

Honest by default

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.

03

Private & offline-friendly

Your data stays yours. The apps favour on-device processing and work when the network doesn't.

Questions

Good to know.

Who is behind AerologHQ?

A current line captain on the A350. The apps and the pack are published under AerologHQ; direct contact is available for substantive questions.

Are the apps free?

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.

Are the apps only for pilots?

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.

Is the DEC Prep Pack a question bank or insider material?

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.

How do updates and refunds work?

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.
