Comments on Morse Code Reader for Android

★★★★★ James Campbell-Gray · Oct 9, 2021

Absolutely the best Morse Decoder in the Play Store (even paid options), both hands down. You must be aware of the needs it has though. The volume of the source must be loud and clear and placed near the mic of the phone for it to work. Not too loud, not too quiet. Play with the variables and you will succeed! It lacks any features beyond decoding, and copy to clipboard function. This one does it the best. Very few errors if any. Other apps decode background noise as false positives. Not this one

Don't be like Jeff is below. This app doesn't care who you are. You'll still need to learn how to use it. If Jeff thinks this app doesn't work quickly, wait until he finds out how hard REAL CW Code is. It ain't going to come so easy Jeff. I've gone through many of these apps and this is currently the best one. Download it, play with it. You need to place it in the correct location and adjust the volume(s) accordingly. Don't give up so easy and run and post that it doesn't work like Jeff did. "Try Harder" it's the new normal. BTW GREAT JOB on the APP please, please add a straight key option or text to morse option!!! Combined this would be AMAZING. Jeff, it could be poor to code or let's say code not up to par. Bad audio quality and or set-up / mic settings etc. You should try again. There really is none better at the moment. If you have a PC try CW Decoder.

The only morse code sound to text translator that works on the entire google play store while everybody making tiktoks apps

Does an excellent job decoding clear and well-formed Morse code audio (quite a feat!). Well done Jacek.

★☆☆☆☆ Jonathan McKaskey · Feb 1, 2024

Did not get any letters correct from any YouTube Morse code examples.

★☆☆☆☆ Gary · Oct 26, 2025

Did not work. Repeater sends same code over and over. This app gave every repeat a different letter?

★☆☆☆☆ Max Y. · Dec 26, 2023

Doesn't work. You should use FFT to catch only audio signals 600hz. Not everything! It's decoding literally everything and noise as well. Useless.

★☆☆☆☆ Bj L · Jul 6, 2025

Random numbers and letters as I changed volume, etc. worthless app. Reads nothing! Tried it again tonight.

Description by Jacek Fedorynski Written by the developer, not by AppBrain. Click to read.

Listens to Morse code through your phone's mic and translates it to text.

The application is somewhat picky about the listening conditions, so if it doesn't work, try adjusting the volume or repositioning the phone in relation to the speaker.

If you can't get it to work, send me an email with a link to a recording of the transmission and I will see if I can improve the application.

Any other feedback welcome.
