Morse Code

Feel every dot and dash.

An Android app that turns any message into Morse code and plays it on your vibration motor.

Morse Code with SOS HEXHAD typed: each letter shown as dots and dashes above the signal waveform

Type it. See it. Hear it.

The same encoder and timing as the app. Your phone vibrates along where the browser allows it; on Android it does, on iPhone you get the tone.

One job, done with care.

A highlight that flows

A mint blob moves from symbol to symbol in time with the motor. It stretches toward the next dash, then settles into it. Across a line it drops over like a bead of liquid.
