Free CW Morse code trainer Android app.

No ads, nags, or in-app purchases. No internet connection required. Fully functional offline learning app.

Using an approach similar to the Koch method, this 10 WPM Morse code CW learning app for Android focuses on listening to Morse code rather than visually learning dots and dashes.

Choose RX or TX Alphanumeric training, or select from Numbers, Prosigns, and Abbreviations.

Alphanumeric = ABCDEFGHIJKLMNOPQRSTUVWXYZ./?0123456789

Numbers = 0123456789

CW Prosigns = BT, HH, K, KN, SK, SOS, AA, AR, AS, CT, NJ, SN

CW Abbreviations = CQ, DE, BK, QTH, OP, UR, RST, 599, HW, FB, WX,ES, TU, 73, CL, QRL

There are two RX interface styles. You may use an external USB or Bluetooth keyboard with either interface.

1) Keypad:

Android plays a character in Morse code and your task is to tap or type the matching character using the app's Default or QWERTY keypad, or external keyboard. Once you have learned a character set with 90% proficiency, a new character is introduced. You will soon have a large pool of characters from which Android will choose, weighted toward those characters learned with a lower proficiency and those with least exposure before selecting randomly from the pool.

2) Copy Pad:

While using the Copy Pad, you are able to receive a string of Morse code characters and write in the whitespace with your finger or stylus. After the string is presented, the app pauses briefly so that you may self-check your accuracy. The whitespace is then automatically cleared and a new string of characters is played. You may change the word length from 1 to 10 characters. The Copy Pad DOES NOT attempt to recognize your handwriting. If an external keyboard is used, then the app will compare the chosen string with what you have typed, displaying incorrect characters in red and those typed correctly in black.

There is one TX interface style.

1) Horizontal lever (straight key):

A character is played in Morse code, and you must tap out that character on the simulated straight lever. When you have learned to send a set of characters with 90% proficiency, a new character is added to the pool.

You should send at a speed that is comfortable while still retaining cadence. For sending fast code, an iambic paddle is helpful.

You can choose to see the code you are tapping out or the characters you have learned. You may also toggle the sound of the characters ON/OFF.

Additionally, you may replace the straight key image with the International Morse code chart.

You may use a real straight key with this app by connecting to your Android device via an easily modified USB mouse.

Alternatively, you may use a 3rd-party device such as My-Key-Mouse USB.

Within the app, several elements respond to certain gestures:

1) Tap the large Character button just below top center to show or hide the presented character. Tap and hold to bring up Stats showing your Hits, Misses, and Correct percent.

2) Tap and hold any character keypad button and that character will be played in Morse code at 10 WPM without registering a hit or a miss.

3) While learning Prosigns or Abbreviations, tap on the definition text to show/hide the meaning of the CW prosign or abbreviation.

4) Tap and hold the Repeat/Resume button in the lower left to adjust keypad font size. Each keypad is individually adjusted. All font sizes may also be changed via your device's Display settings.

5) To reset your stats for a particular character set, from the Home Screen tap and hold the desired character set and you will be asked to confirm the action.

Lastly, if you have questions, suggestions, concerns, complaints or otherwise, please contact appsKG9E@gmail.com

Comments on 10 WPM CW Morse code trainer for Android

★★★★★ Ronald F · Feb 6, 2026

By far the best CW app I've ever used. You actually need to learn each step in order to continue to the next letter. I noticed that when I focused more on the actual sound of the letter instead of counting the dits and dahs it instantly became easier to recall. And I love how it builds up from each previous letter. It's not predictable, yet easy to learn. I'm trying to push myself by answering as fast as possible. This gives me an illusion of a faster paste to recall and helps not to count.

★★★★★ Mr X · Jan 5, 2023

Fabu app. This works fine when I'm not able to sit in front of my rig with a Vibroplex paddle and practice Morse.

★★★★★ 1960 Jaguar Sedan · Jun 3, 2022

Excellent Morse code training app. Looking forward to faster speeds.

★★☆☆☆ Jonathan Winokur · Aug 27, 2017

Several things I wish were different. Please add a slight delay between the human response and the next letter! I also wish that I could set the level to start at. I've used other apps and know many of the letters. Repeating ".-" 10 times then moving on to ".-"&"." 10 more times before adding the next one caused me to lose interest. I'm also not sure what the point of the TX option is if you play the sound first... it's parroting not thinking.
