Morse Code App

This site is a free Morse code app that works in any browser and installs to your phone or computer in one tap — no app store, no cost. Once installed it opens full-screen and works offline, so you can translate, play audio, and flash light anywhere.

Install it in one tap

Because this is a Progressive Web App (PWA), you can add it to your home screen and use it like a native app:

On Android (Chrome): tap the menu (⋮) and choose "Install app" or "Add to Home screen."

On iPhone/iPad (Safari): tap the Share button and choose "Add to Home Screen."

On desktop (Chrome/Edge): click the install icon in the address bar.

After installing, it launches from your home screen or app drawer and runs offline.

What the app does

The app includes the full toolkit: two-way text and Morse translation, audio playback and decoding, a flashing-light signaller, and reference charts for the alphabet and numbers. Everything runs on your device, so your messages stay private and it keeps working without a connection.

Why a web app instead of a download

A web app updates automatically, takes almost no storage, and works the same on every device. There's nothing to sideload and no permissions to worry about beyond the mic (only if you decode audio) and camera flash (only if you use the torch). For most people it's simpler and safer than hunting for a separate download.
