About this app

Decodes Morse Code audio to text. Optimized for decoding weak, fading signals in the noise and interference, especially on the Amateur Radio bands. Optionally highlights Ham callsigns and keywords. The audio may come either from the built-in microphone or from another device, such as a radio, via an audio cable. Decoding is performed using the same algorithms as used in CW Skimmer.

Terrific app that performs exceptionally well at decoding Morse. Its ability to decode properly and form cohesive words depends much on the skill of the person sending the code and how consisted each character is. transmitted. Thanks for the effort that went into creating and maintain this product. Stay within the specs on the help pages for the best performance.

Love this app. It works well. Any way to introduce a monitor function in the next version? That way, you can plug a single TRRS splitter into the phone, and use it to both inject the audio from the radio AND listen with a pair of headphones. No extra cables or plug swapping required. Thx.

App shows the dots and dashes as received but doesn't ever convert them to characters. I'm using an iambic keyer and the frequency is within range. If I tap on the screen I get random characters. Paid $5 for the ad-free version thinking that might be the answer to more settings but alas it seems like I just lost $5. This is on a Samsung Galaxy Note 10+
