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.

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.

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.

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?

Each app has its own pricing on its store page — several offer a free tier with an optional upgrade. Tap through to the App Store or Google Play for current details.

Is Keepr just for pilots?

No — Keepr is for everyone. It tracks return windows and warranties so you don't lose money to missed deadlines, 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.
