Morse Practice
[Click to Start]
Try the new Android app with lower latency and support for more keyer algorithms: Download from Google Play
Supported inputs: keyboard, touch screen, mouse, or a paddle with usb adapter.

For mouse left/right-click keying or USB-to-mouse paddle adapter, leave the mouse pointer above the left app button, left/right click or paddle will work.

For an USB-to-keyboard paddle adapter it works out of the box (e.g. tested with VBand) - let me know if it doesn't.

Strict mode requires the proper timing between letters, non-strict mode allows faster manipulation.

Common issues: If the sound is too clickety in your device, try the 'No-click' option. If latency is too high, try another browser (e.g. Firefox).
