How to use DotDotDoit

Send a message

Turn any text into Morse and play it out however you like.

1. Type your message in the Send box.
2. Pick an output: sound (beeps), torch flashes, a full-screen strobe, vibration, or Both (sound + torch).
3. Adjust the WPM slider for speed, and press Play.

Torch speed is capped a little for hardware safety, so flashes run slightly slower than beeps.

Send SOS

One tap sends the universal distress pattern on every channel at once.

1. Open SOS mode.
2. Press the SOS button — the app plays ··· −−− ··· on sound, flash and vibration together.
3. It loops until you stop it.

A great demo and a real skill — but for fun and learning, not a substitute for real emergency equipment.

Tap it out yourself

The tap key reads your own rhythm and decodes it.

1. Open the Tap key.
2. Press briefly for a dot, hold for a dash.
3. Give it a few even taps so it can lock onto your timing; then keep going.

You can replay what you tapped via sound or torch, and export it.

Decode beeps (audio)

Point the mic at a Morse tone and read the text as it arrives.

1. Open Receive → Audio and grant microphone access.
2. Aim the phone at the sound source.
3. Watch the live signal waterfall and the text appear in real time.

Find a quiet spot — background noise competes with the tone.

Decode a blinking light

Aim the camera at a flashing light to read it.

1. Open Receive → Light and grant camera access.
2. Frame the blinking light steadily.
3. Brace your elbows or rest the phone — a steady aim reads best.

Decode a photo

Read dots and dashes straight out of a picture.

1. Open Receive → Photo.
2. Pick a clear, high-contrast image of the code.
3. The app reads the pattern and shows the text.

Learn the alphabet

Use the reference table and the practice trainer together.

1. Browse the Reference table — tap any row to hear it.
2. Open Practice and start with a couple of letters (the Koch method).
3. Turn on Farnsworth to hear characters at full speed with wider gaps.

Prefer the browser? Try the Learn page and the translator first.

Make a Morse wallpaper or GIF

Turn your name (or any message) into something to keep or share.

1. Type your message, then choose Send → Image.
2. Pick Card, Wallpaper, or animated GIF.
3. Save it or share it.

Add the SOS home-screen widget (Android)

One tap from your home screen fires SOS.

1. Long-press your home screen.
2. Choose Widgets, then DotDotDoit.
3. Drag the SOS widget onto your home screen.
