Morse code is a method of transmitting textual information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the Roman alphabet, the Arabic numerals and a small set of punctuation and procedural signals as standardized sequences of short and long signals called "dots" and "dashes" respectively, or "dits" and "dahs". Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.
Each character (letter or numeral) is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The dot duration is the basic unit of time measurement in code transmission.
Any suggestion/feedback is welcome. Thanks! If you got any problems with our app please send us an e-mail, we will do our best to help you.
Morse Code Keyer allows text entry from Morse code input. It features a CW paddle type interface with a dit key and a dash key to enter the characters. This is good way to practice generating Morse code. This practice can solidify skills in learning and forming the Morse code characters. This skill can translate directly to sending CW on the ham radio bands if you have an amateur radio license. If you don't have a license, it can be fun to impress your friends with messages you composed with Morse code.
-Full Iambic keyer.
-Send entered text by SMS or email
-Iambic mode can be turned on and off.
-Adjustable auto word spacing.
-Easy adjustment of side tone frequency (200 – 1500Hz).
-Easy adjustment of WPM.
-Adjustment of sound envelope to affect quality of sound.
-Stand alone keyboard in pro version.
This is the free version and has the same functionality as the pro version, but contains ads and does not contain a stand alone keyer. Using this app is a good way to evaluate if this works well on your device.
The keyer is a full Iambic keyer with one caveat. If you push the dah key, then press the dit key, the characters will alternate like an Iambic keyer. The issue is if you lift your finger off of the dah key, the output will stop instead of continuing to repeat the dit character. This is due to the way Android multi-touch works. In the same scenario, lifting the dit finger will allow the dah characters to continue.
Morse Code Keyer features a settings screen where screen layout, keyer and sound settings are adjustable.
The layout options consist of turning on and off a small popup window. This window will show the dits and dahs as they are entered. The side of the screen the dit key is on can be adjusted (right or left). There is also an option that affects the visibility of the words per minute (WPM) slider.
For the keyer you can adjust whether or not the keys should repeat. For example, holding the dah key repeats the dah key at the current WPM setting. Iambic mode is also adjustable. With this on and when both keys are pressed, the dits and dahs will alternate. The auto spacing feature is also adjustable. This adds spaces automatically at word boundaries.
The sound setting that is adjustable is the rise and fall time envelope percentage. The percentage is of the total dit time. Longer values will make a softer sound, while shorter values give the sound more punch.
Thank you for your interest in Morse Code Keyer. If you any issues what so ever, please contact me rather than leave negative feedback. I will work with you to resolve the issues.
☺ Faster Than Morse (FTM) helps you to ☺
- train your morse code skills in Race against time mode
- test your Morse listening ability to receive a complex message
- quickly and easily convert test to morse code and back, flash the message using the flash in your camera or beep it
☺ And more: ☺
- sharing is supported. You can select a text in email client, send it via “share” button to the FTM, convert to the morse code and via “share” in the FTM send to any eg Facebook/SMS message,...
- you can edit the Morse code table
- fits nicely even on the smallest phone displays.
- configurable speed of sound output in words per minute. Farnsworth timing is supported.
- tracking of mistakes; symbols you do not know very well are repeated more often to train them
If you like the application, rate it with five stars :-).
I am not responsible for any damage caused by the application.
WARNING: Excessive usage of flash and vibrations can discharge your smart phone battery faster than usual.
The application is tested on HTC Desire HD. If it does not work on your device, let me know via email and I will try to debug and solve the issue. I will be also grateful for any your comments.

-A dot is 1 unit, so in the case of this app, you set the Dot Time.
-A dash is 3 units
-Parts of a letter have a 1 unit pause
-Between two letters in a word is a 3 unit pause
-A space is a 7 unit pause
When the Morse code is played, dashes and dots are represented through periods where the light is turned off and pauses are periods where the light is on.
As of version 1.02, the characters A-Z and 0-9 are supported. Letters are not case sensitive.
Idea provided by Dr. Nathaniel Abraham
Enter a message and the phone will display and vibrate the message in Morse Code.
Turn on the SMS option and the application will vibrate any incoming SMS messages for you in Morse Code.
(This application is free but backed by ads, and hence needs Internet access.)
