About this app

Send Morse code by tapping it out on a handsomely crafted oscillator or convert text to Morse and send light and tonal signals.

The text to Morse feature allows you to easily set the transmission rate. Adjust the number of words per minute by setting the length of dots and dashes and the duration of pauses between words and characters.

Messages can be set to repeat automatically.

This Morse code oscillator can convert your key taps to English based on your level of experience: beginner, intermediate or expert. The oscillator is great for ham radio operators and anyone who wants to learn and practice Morse code. The app can also come in handy in some situations if you ever need to send an emergency SOS signal when phone service is not available.

English alphabet and standard numeric characters are supported.

I'm very new to Morse code, so I can't really comment on how realistic the oscillator is, but the feature to choose your speed is nice as well as an option to show what you're "typing" on screen in realtime. The privacy policy should be clear about what kind of "anonymized data" is sold to 3rd parties. The fact that it is so ambiguous is a little concerning.

In Google Play Store, amongst several dozens of executables supposedly intended for working with Morse code, this is THE ONLY ONE that really reproduces the functions, and even the look, of a true Morse keyer. There is another keyer, but that one has a button for dots and another button for dashes, which is NOT how a Morse keyer operates. This keyer by Disciple Skies correctly uses only one button. The operator must be skilled for sending either a dot or a dash by the duration of touching.

This app is very good. Simple to use and able to send both light and sound. Also has a built in SOS mode that repeatedly sends SOS. Would be better if it had fewer adds however.
