Description
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.

It works but it pick up background noise and only works well with actual beeps and slash not taps

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.

Reads st only about 50% accuracy. Needs much improvement.

Piece of Junk. Can't get one letter right. Even shows letters when no morse code is being sent. It is good for wasting space on your phone, I'll give it that.

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.
