Store description excerpt

SignalCrafter is an offline field-signaling kit for learning, planning, and practicing classic non-network communication. The app combines a Morse broadcaster, signal-flag hoist composer, reference almanac, and drills in a crisp, high-contrast interface built for quick use outdoors. PRO FIELD SIGNALING TOOLS - Timed Morse transmit plans with WPM, repeat count, pause interval, word count, unit count, and total send duration. - Morse broadcast as screen flash, tone, haptic pulse, or any combination. - Field protocol presets for SOS, Mayday, medical help, food/water, position unknown, status, repeat, and go-ahead. - A-Z signal-flag hoist builder with optional substitute flags for repeated letters. - Hoist readback, skipped-character warnings, and tappable flag details. OFFLINE ALMANAC - International Morse code letters, numerals, prosigns, and practice words. - NATO/ICAO phonetic alphabet with spoken pronunciation. - International maritime signal flags and single-flag meanings. - Ground-to-air symbols for visual rescue signaling reference. - Beaufort wind scale for reading sea and land conditions. TRAIN UNTIL IT STICKS Use the Drill tab to practice Morse, flags, and phonetics with a running streak and best-streak memory. BUILT FOR LOW CONNECTIVITY No account, no cloud, no ads, no tracking, and no network features are required. SignalCrafter stores preferences locally and works in airplane mode. SignalCrafter is an educational reference and training tool. It is not a certified emergency beacon, marine radio, aircraft signal device, or substitute for official procedures or proper emergency equipment.
