## What is Halyarde?

Halyarde is an offline maritime visual-signal field reference and training studio for sailors, educators, scouts, and signal enthusiasts.

SEARCH A SOURCE-PINNED SIGNAL CATALOG

Browse 628 two-letter International Code of Signals entries transcribed from the U.S. National Geospatial-Intelligence Agency's Pub. 102. Search by code or meaning, filter by operational category, save favorites, and open each signal's publication page reference.

COMPOSE AND DECODE FLAG HOISTS

Type a word or short message to build a vertical signal-flag hoist, or switch to Decode and construct one flag by flag. Review the Signal Deck for flag count, breaks, phonetic coverage, priority notes, and a suggested drill. Save or share a rendered hoist image when you choose.

TRAIN WHERE RECALL IS WEAKEST

Practice signal flags, semaphore, or two-letter code signals. Adaptive sessions prioritize unseen and weaker items, record answer history on device, and surface accuracy, mastered items, and a focused review queue.

KEEP A COMPLETE FIELD REFERENCE

- Alphabet flags, numeral pennants, and substitute pennants
- Semaphore positions for A through Z
- ICAO phonetic alphabet
- Morse reference with optional sound and haptic feedback
- Searchable favorites for rapid field access
- Source links and scope notes inside the app

Halyarde's core reference and training tools work without an internet connection. There is no account, subscription, advertising, analytics, or tracking. Training progress and favorites stay on your device. Photo-library access is requested only when you choose to save a generated hoist image.

Halyarde is for education and reference. For real marine operations, follow current official publications and instructions from the relevant authorities.


## Version history (last 3 releases)

### 1.2 — 2026-08-21

Halyarde 1.2 adds a searchable offline catalog of 628 two-letter International Code of Signals entries, each pinned to its Pub. 102 source page. New category filters, favorites, signal details, and adaptive training make it faster to find a code and practice what you have not mastered. This update also improves iPad layouts, accessibility, generated plate branding, and source transparency.

### 1.1 — 2026-06-28

Version 1.1 adds Signal Deck, a pro training report for every flag hoist. It summarizes flag count, word breaks, phonetic coverage, urgent/caution signal notes, and a recommended drill so learners can practice the hoist instead of only viewing it. This update also refreshes metadata, screenshots, and public support/privacy pages.

### 1.0 — 2026-06-24
