MorseBook

MorseBook turns your iPhone into a complete Morse trainer: a CW reference you can hear, a straight key you can send on, copy drills that keep you honest, and a coach for the moments a rhythm refuses to stick. Every entry plays real ITU-timed audio - dits, dahs, and proper spacing at your speed. Read each rhythm the way operators voice it (di-DAH for A, DAH-di-di-dit for B), then press the straight key and watch your own sending decoded live on screen. WHAT IS INCLUDED - Complete reference: A-Z, 0-9, punctuation, prosigns (SOS, AR, SK), and classic signals (CQ, QRZ, 73) - Audio playback for every entry with adjustable speed (5-30 WPM) and sidetone pitch - Straight-key practice pad that decodes your keying as you send - Encode and decode drills with reveal-when-ready answers - Per-entry mnemonics, timing breakdowns, confusion pairs, and operating history - Ask the Morse coach about rhythm, confusion pairs, and practice plans - Personal practice log to keep notes between sessions - No login, no invite code, no external account required FREE AND PRO The free app includes the full codebook with audio, the straight key, practice drills, the practice log, and 3 coach asks per day.
