Morse Code Trainer: Learn CW

This morse code trainer teaches you by ear, the way radio operators do. Open it and the first thing you see is your next lesson: the newest character, how it sounds (dah dit dah), and how many of your characters you have already learned. Tap Start lesson and listen. A clean tone plays one character, you pick it from the grid, and after 20 answers you get a score. Reach 90% and the next character joins the set. That is the Koch method, the quickest way to learn Morse code without memorising a chart.

A good cw trainer also needs real copy practice. Here you hear groups of five characters, type what you caught, and see a score character by character, so one slip never wrecks the rest. Speed runs from 5 to 30 WPM with Farnsworth spacing: letters stay fast while the gaps stretch, which stops your ear from counting dits. Send practice turns the screen into a key: tap dits and dahs, hear a sidetone, and see your dit and dah lengths measured against the ideal 1 to 3 ratio.

Need a morse translator? Type text to get dots and dashes, or paste Morse and read it back. It is a morse translator that also plays the result as sound. Pro adds flashlight and vibration output, so you can send a message across a dark room. The free plan covers the first 10 characters, the translator and the full character chart. For ham radio, Pro adds callsign drills and QSO phrases such as CQ calls, signal reports and sign-offs.

Learn Morse code at your own pace: the first 10 characters are free, and Pro opens all 40+ characters with a yearly plan that starts with a 7-day free trial, or one lifetime purchase. Your progress is kept per character on your phone, with a day streak. Cancel the yearly plan anytime in Google Play. This cw trainer and morse code trainer never asks you to sign up.
