Android Morse Decoder App by Jacek Fedorynski

I came across this free app for Android phones called (literally) "Morse Code Reader" and was a free-bee from Google Play store. The launch icon has a picture of a Walrus for some unknown reason. This particular one was written by Jacek Fedorynski.

There is no help or info file. After install you run it and it starts decoding straight away. It does not seem to use a tone selection, but appears to use audio level derived decoding. There is a red line that appears across the audio level VU display, and that line seems to be an average of some kind. Anything above the line is 'high', anything below the line is 'low', so it just looks at the changing high/low level of the audio to work out what the CW tone level is at that point.

On the face of it it might sound a bit naff, but I've used it with a number of online sources and actual transceivers, and I've found the decode seems to work amazingly well in most cases.
 
Here's a photo of the App decoding the output from a Kent Morse Tutor. Obviously the tutor was just set for random letters and numbers mixed.

If you look closely at the image you can just make out the red 'average' line I mentioned above.

I did try to find some off-air CW but the bands seem a bit dire at the moment. The few bits of CW I did find were not very well sent, the op's were merging letters and words together.
 
Seems a very popular app on Google Play store (100,000+ downloads).

Installed without a hitch. Good solid copy of BBC News at 15 wpm from Morse Code Practice Tool

I prefer to listen to morse over headphones but will use a splitter cable to my small speaker next time I'm QSOing to see how it copes with real morse.
