MorseBook vs Morse Code Trainer

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.

Every inch of the screen is your straight key. Press anywhere to send — it lights up and plays a sidetone. RECEIVE — the Koch method with Farnsworth timing. Start with two characters at real-world speed (15-25 WPM) and unlock the next at 90% accuracy, through 40 levels. The answer pad shows only the characters you have learned, so there is nothing to second-guess. SEND — real-time decoding with automatic dit/dah calibration. Watch yourself descend the Morse code tree with every keypress: hold for left, tap for right, with dot and dash waypoints always showing where the next press leads. Targets grow from single letters to common CW abbreviations and callsigns. CHART — the full alphabet, numbers and punctuation. Tap any row to hear it at your configured speed and tone. SETTINGS — character speed 15-25 WPM, effective (Farnsworth) speed 5-15 WPM, sidetone 400-1000 Hz, key haptics. Volume follows the silent switch. PRICING — all training features are free, with no ads. A one-time Pro (Supporter Pack) purchase adds alternate app icons, theme colors and a 30-day progress chart. Everything stays on your device — no account, no tracking, fully offline.
