Two different apps live on this site. This page is about the Author Operations Center, the publishing command center. The SPARTAN CODE App — the companion to the books — is already available on the App Store.

Built by an independent author, for independent authors. It grew from the system Frank Castle uses to run his own books — one operational source of truth for books, publishing, press, media, events, venues, marketing, websites, readers, and analytics.

What it does

• Command dashboard — current work, publishing health, issues, and deadlines on one screen.
• Canonical title records — print, ebook, and audiobook ISBN editions grouped beneath one book.
• ISBN registry — Bowker block allocation, reservation, retirement protection, portable CSV/JSON.
• Platform status board — 21 author platforms (Bowker, Amazon, IngramSpark, Goodreads, Tertulia, the Library of Congress…) with five clear states coded by symbol shape and label, never color alone.
• Transparency console — every metadata check prints the exact request, the response, and whether each value was inherited from a platform or generated in your catalog. Tap-to-run command scripts; nothing to memorize.
• Copyright operations — preparation checklists, filing records, and publication-date reminders.
• Author operations — press kit, media, speaking, events, venue CRM, reviews, interviews, website, and reader missions.

Private by design

No account. No cloud database. No advertising, telemetry, or tracking. Your catalog lives on your device; optional lookups run only when you ask. Platform sign-ins happen in Safari, where Apple Passwords autofills — the app never sees or stores your passwords. Details in the privacy policy.

Coming to the App Store for iPadOS 18+ and macOS 15+.
