Morse Code Flashlight
On Android, your phone's flashlight flashes your message in Morse; on iPhone, where browsers cannot control the flashlight, the whole screen flashes instead. Type a message and press Play.

Pause for a letter gap, pause longer for a word gap. On a computer the space bar works too. Timing follows the speed in Settings.
Decode Morse from sound or a picture
Play a Morse tone near the microphone, or open a recording. The decoder finds the pitch and the speed by itself and works best on a clean tone between 300 and 1500 Hz. An image works when the dots and dashes are solid shapes on a plain background, like a screenshot or a printed card. Nothing is uploaded: everything is processed on your device.
Set overall speed lower than letter speed for Farnsworth timing: letters stay quick, the gaps get longer. This is how most people learn.
Morse code chart
Tap any character to hear it.
Letters
Numbers
Punctuation (ITU)
In common use, not ITU
National letters, not ITU
Procedural signals (prosigns)
Sent as one signal with no gap between the letters. Type them in angle brackets, like <SK>.
How it works
Light turns the whole screen into a white signal lamp that switches on for each dot and dash. Torch switches your phone's own flashlight on and off: this works in Chrome on Android, because iPhone browsers do not let a web page control the flashlight. On an iPhone, use Light.
Tips for signalling with light
- Slow down: set the speed to 10 WPM or less in Speed, tone and sound. Light is harder to read than sound.
- Use Loop to repeat the message until the other side answers.
- At night, turn the screen brightness to maximum and point the phone straight at the receiver.
