OpenShack: Learn Morse Code

OpenShack

About this app

Learn Morse code by ear, one character at a time. Want to learn CW, the Morse code used in amateur radio? Start with listening lessons, try sending, then talk with other people in Morse Chat. No radio or extra hardware needed.

LEARN BY LISTENING
Start with a few letters. Listen, type what you hear and add more characters as you improve. The Koch method teaches each character by its sound. Set your own speed and use extra space between characters (Farnsworth spacing) when you need more time.

PRACTISE SENDING
Use the on-screen paddle to send dots and dashes. Check the timing of your characters and spaces. For practice with a physical paddle, connect it through an optional OpenShack Box.

SEE YOUR PROGRESS
Review your accuracy and the characters that need more work. Lessons, settings and progress stay on your device. Export and import your profiles, including compatible OpenShack desktop trainer profiles.

MORSE CHAT
Join a room and practise with other people over the internet. Type a message to send it as Morse code, or use the screen key. Share a lobby or room link and QR code with a friend: they can join in a web browser. No App needed. Connect with a callsign or name.

KEEP PRACTISING
Advanced Practice offers characters, groups, words and amateur-radio callsigns at your chosen speed. It has its own profile, so your beginner lesson progress stays separate.

Lessons and Advanced Practice work offline. Morse Chat, Network Box connections and website links need internet access. Training results are not posted to public leaderboards.

English interface for phones and tablets. One purchase includes all three modes. No ads, subscription or account registration.

Use your own paddle with the optional OpenShack Box. The Box is sold separately and connects via Bluetooth, USB or Wi-Fi. The About screen links to the manual and help.
