iPhone
The coach now quotes the ITU table instead of recalling it - ask it to separate B from 6 and the patterns come back right.
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

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The Morse coach now runs on MorseBook's own server, and it no longer has to work out a code from memory: the full International table is given to it, so when you ask how to separate B from 6 it quotes -... and -.... correctly instead of guessing.
Also in this update:
- Privacy, Terms and Support have moved to morsecode.keenshift.ai, and Support is now linked from Settings.
- Clearer wording on the Pro screen about what stays free: the codebook, the ITU audio, the straight key and the drills are free and stay free. Pro only lifts the daily coach limit and the practice-note limit.
