$2.99 · Designed for iPad. Not verified for macOS.
Compose maritime flag hoists, decode signals, drill semaphore, and use the new Signal Deck to practice urgent and routine hoists.
Halyard is an offline maritime signal-flag studio for learning, composing, and practicing visual signals.
Type a word or short message and Halyard builds a vertical International Code of Signals flag hoist. Decode mode lets you tap flags and read them back. The new Signal Deck gives each hoist a practical training readout: flag count, word breaks, phonetic coverage, Morse coverage, urgent/caution flag notes, and a recommended drill.
What is included:
- Flag Hoist Composer for letters and numerals
- Decode mode for building a hoist by tapping flags
- Signal Deck training report for every hoist
- ICS alphabet flags and numeral pennants
- Semaphore reference for the alphabet
- NATO/ICAO phonetic alphabet reference
- Morse reference with bundled audio/haptic practice
- Recognition quiz for flags and semaphore
- Standards/source links inside Quick Reference
- Fully offline design with no account and no tracking
Halyard is designed for sailors, scouts, educators, signal enthusiasts, and anyone who wants to learn maritime visual communication. It is a reference and training app only. For real marine operations, follow current official publications and local authority instructions.
Everything stays on device. Halyard has no account system, no analytics, no tracking, and no third-party SDKs.

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.
