## Description

Set the tone level right from Settings, and let practice carry you from one
word set to the next.

Morse code becomes easier to remember when you hear it, key it, and understand how its patterns connect. Morse Master is a hands-on learning game that helps you explore the Morse tree and build practical skill through guided lessons and repeated keying practice.

New learners can start with an interactive introduction to dits (·) and dahs (—). If you already know the basics, adjust the speed and timing to create a practice setup that matches your level.

Key features

• Explore letter relationships on a visual Morse tree
• Follow a guided, interactive introduction for beginners
• Practice letters, numbers, or a combination of both
• Build fluency with word-based repetition and Morse key input
• Adjust WPM, dit/dah timing threshold, and word spacing
• Practice with straight-key and iambic-paddle input styles
• Customize sidetone, sound character, haptics, and Morse hints
• Review learning progress, statistics, and personal records
• Use the app in English or Korean
• Optionally sign in with Apple or Google to sync learning progress

Morse Master is designed for

• Beginners learning Morse code for the first time
• CW and amateur radio enthusiasts
• Learners who want to turn memorized patterns into practical keying skill
• Anyone working to improve speed and accuracy through regular practice

No account is required for the core learning experience. Sign-in is optional and is only needed when you want to synchronize learning progress across devices. The iOS version is free and contains no ads, in-app purchases, or subscriptions.
