Morse Code Trainer (Learn CW)

About this app

**Free: no ads, no privacy intrusion, no hidden fees, fully open source**

The recommended way to learn Morse code (cw) is not by remembering dots and dashes but by remembering the sound.

This app plays character, words and phrases in Morse code, gives you a brief moment of time to recognize it and then speaks out loud the answer. Allowing you to learn Morse code without having to look at or interact with your phone. Hopefully the app helps you and me learn to copy Morse code in our heads.

Features:
* User setting to repeat character/word/phrases multiple times before going to the next one.
* User setting to give hint before/after Morse code. Allows you to practice reading and generating Morse code in your head.
* Your own custom word list (see below).
* Set speed, farnsworth spacing, pitch, and more.
* Dark mode, to match your phones theme.

The app comes with the following word lists:
* abc.txt - contains the alphabet (a to z)
* numbers.txt - contains numbers (1 to 9 and 0)
* symbols.txt - period, stoke and question mark
* abc_numbers_symbols.txt - combination of the three files above
* memory_words.txt - some memory words

The app requires write access to your device's USB storage in order to work. The directory "Claus' Morse Trainer" will be created for the words lists. The directory can be safely deleted after you uninstall the program.

You can create your own custom files with characters, words or phrases that you want to learn. Just create a text file with each character, word or phrase on a separate line. If the Morse text and spoken text is different then separate them with a vertical pipe "|". E.g.:
tu|thank you

Tip: The Google Text-to-speech engine sounds quite a bit better than the Samsung Text-to-speech engine that is enabled by default.

This app is created of love of coding and amateur radio. Done in a professional manner but purely as a hobby. To enhance your and my ability "speak" Morse code and to to operate CW on the air waves. Not only is the app free, but the source code is viewable on Github. No data is collected by the app, so there is no need for a privacy policy.

Please report any issues and errors via GitHub ( https://github.com/cniesen/morsetrainer ). Ideas and code contributions to improve the Morse code trainer are welcome as well.

Ratings and reviews

Love it. Suggested improvements: 1. Sleep timer 2. Add more prosigns such as AR, SK, BT 3. Turn off voice 4. Under "memory words" TU should be Thank You and not To You 5. Sliders in settings are difficult to use. E.G. change voice time from 300ms to 500ms.It is difficult to make such adjustments. Above are just some suggestions and not a critique. The app is awesome and has greatly helped me improve my CW skills. Thank you for creating it!!! A+A+A+A+A+

Exactly what I've been looking for in a CW trainer app. Google speech provides much better results than Samsung for announcing the characters. App needs a little refinement still....but with some time, it'll get there. I love the simple UI and no ads. As it is now, it does exactly what I want.....73 de WØFW

Learn Morse code the only way it should be learned - by sound, not by dots, dashes or, God forbid, some other more elaborate visual crutch... I actually made something similar to this way back on my old SonyEricsson, and was very pleased fo see this app on Google play. Well done, to the point, no bells and whistles, just Morse. Extra kudos for no ads and github link.

What's new

Added vocalize setting to turn on/of spoken text.
