Master letters, morse, and sound

Drill every direction—character, written morse, and audio—and back again. Spaced repetition brings back what you miss sooner and spaces out what you know so it stays sharp.

Learn— New material, due reviews, and light upkeep on what you already know.
Mastery— Confidence by symbol and skill; open any character for detail.
Settings— Choose question types, deck scope, audio pitch and speed. At least one question type stays on.

Start learning Mastery dashboard

Tracks each skill separately

Each kind of link—letter, morse text, and audio—is practiced on its own, so the app can spend more time on the connections you personally find hardest.

Easier questions at first

You will see multiple-choice prompts when you are still learning; as you improve, the same ideas show up as type-in questions for a stronger memory check.

Smart review timing

Get something right and the app waits longer before asking again; miss it and that item comes back sooner so you can relearn it while it is fresh.

Symbol reference

53 characters with International Morse. Filter the list; the learning deck follows your Settings (scope may differ).
