About this app

Decipher Morse code to text or text to Morse code

Turn any text into Morse code, or translate Morse code to text and hear the results.

• Clean, modern app design and interface. • Made to be simple to use for everyone. • Realtime translation: type in the word or code and have it translated immediately. • Decode from Morse to text, or text to Morse. • Press the speaker button to hear the code. • Copy the text by pressing the "Copy" button. • Type in dot and dash using our built-in Morse keyboard. • Libre software (https://github.com/Crazy-Marvin/Morse) + More features planned.

Don’t let the special characters or dots and dashes befuddle you.

Morse code is a system to encode letters and numbers to dash and dot signs. The duration of the dash is three times the duration of a dot. Each dot or dash is followed by period of signal absence, called a space, equal to the dot duration.

Morse code was first used for communicating via telegraph. The most well-known Morse code is SOS, which is used to signal an emergency. Aside from typing dots and dashed, you can also signal Morse code by turning light on and off, sounding a horn or tapping, etc. All means of transmitting Mores code require the recipient understands it. If not, our app may be used to find out the message, password, secret number, or any info you want to relay. Nowadays, even though the use of the telegraph has been widely superseded by other communication technologies, Morse code still finds its place in the lives of various individuals. Due to its presence in popular culture, Morse code has been featured in movies, games, and other medias as a simple way to encode messages, inspiring fans to research and explore the language as part of fun, puzzle-solving activities. This makes it useful even in cryptography or cryptogram events as a handy encoding tool.

1. Tell others when you are in a dangerous situation (SOS). 2. Hide your secret number or password via dots and dashes. 3. Cipher or decipher hidden clues in games. 4. Learn cryptography or cryptogram through learning Morse codes. 5. Become a codebreaker by breaking secret codes in real time translation. 6. Create a secret number. + Many more

Installation Guide

1

Open Settings on your Android device

2

Go to Security → Unknown sources (or Install unknown apps)

3

Enable "Allow from this source" for your browser or file manager

4

Open the downloaded APK file from your Downloads folder

5

Tap "Install" and wait for installation to complete

6

Launch the app from your home screen

Make sure to re-enable Unknown Sources restrictions after installation for security.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be rocks.poopjournal.morse is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

If the current release misbehaves, 2.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Morse first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Morse, and a listing is removed when the evidence for it stops holding up.
