Read full description

The app has several parts: - Morse Trainer: learn CW one character at a time, copying and sending - Advanced Trainer: once you know your alphabet, work on character groups, words, ham radio abbreviations and callsigns, copying and sending - Morse Decoder: reads your sending back to you - Morse Sender: turns text into CW audio, typed live or by copy and paste - Morse Chat: send and decode CW 1:1 with other ops, multi-user, with your own rooms Note: You can send with the on-screen key or with a connected straight key or paddle. There are several hardware options. The most versatile and accurate is the OpenShack Box from openshack.com, but interfaces that emulate a keyboard, such as VBand and Morserino, work too. LEARN MORSE CODE A complete CW course for beginners in 40 lessons. Set your speed and spacing. Farnsworth spacing gives you more time to copy. PRACTISE YOUR SENDING Send with the on-screen key or a connected key. The app shows how even your characters and spacing are, and where your fist departs from standard timing. YOUR PROGRESS The start screen shows your lesson, your practice time and how solid each learned character is. Review your mistakes and drill the difficult characters. Progress and settings stay on your device. Back up and restore your profiles. Compatible trainer profiles from OpenShack for Windows can be imported too. TRAINER FOR ADVANCED OPS With the Advanced Trainer you work on characters, groups, words, ham radio abbreviations and callsigns. Copy what you hear and type it in, or key it back. Set your speed, with longer spacing (Farnsworth) if you want it, and train copying or sending. MORSE DECODER Send with the on-screen key or a connected key and check your fist. The app shows what you send as text. Turn on 'Allow uneven timing' while your spacing still varies. MORSE SENDER Type or paste text and hear it as CW at 5 to 100 WPM, with Farnsworth spacing if you want it. With Immediate on, each character sounds as you type. Sent text is highlighted and the field scrolls along. MORSE CHAT Practise CW or ragchew with other ops over the internet. Type your message, or send with the on-screen key or a connected key. Invite others to a room by link or QR code. They can join free in a browser, no app needed. A callsign or name is all you need to connect. English interface for iPhone and iPad. One purchase includes all five parts. No subscription, no ads and no account registration. With the optional OpenShack Box you can use your own paddle and analyse your fist to the millisecond. The Box also works as a rig keyer and for remote operation. It is sold separately and connects via Bluetooth or Wi-Fi. You'll find the manual and help under About.
