Description
The HotPaw Morse Code Decoder translates Morse Code sound into text. Just use the microphone or headset input on your iPhone or iPad for the audio signal input, and watch decoded text appear.
The Morse Code Decoder includes both an automatic decoding mode, plus manual controls to allow the decoding of weaker signals in noise and QRM. Manually adjustable parameters include the frequency of the audio filter, the WPM dot/dash speed used for detecting characters, the threshold level of background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters.
The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones. Use the optional narrow-band DSP audio filter to help filter out background noise. The audio filter works for tone frequencies from 300 to 2400 Hz. Please do not try to decode tones outside this range.
The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed. You can also manually set the WPM code speed if the automatic speed detection guesses incorrectly. A QRQ High Speed WPM mode setting allows decoding much higher WPM speeds in the range of 30 to 80 WPM.
Please aim your iPhone microphone at the Morse Code sound source so that the iPhone's noise cancelling microphone doesn't cancel it out. You can see if sound is getting to the iPhone by seeing a peak in the spectrum display. Please use the manual settings if automatic decoding does not adjust to the frequency, WPM. or background noise threshold level properly. Decoding will not work if the audio filter or WPM are set incorrectly, or there is a lot of background noise or room echoes above the threshold setting. Please see the help file on the HotPaw website for hints as to how to solve decoding issues.

Everything is an E
At least every other letter this app detects is an E. If there is background noise you have no chance, it will get no sound or it will get all the wrong sounds. I do not recommend getting this app.
Red Culver,
Works great if you set it right.
I have a Yaesu ft 857. I hav to change my receiver to 700hz or the iPhone WILL NOT hear the CW. I also find it useful to set the manual speed a little above the current words per minute. A person can spend his whole life developing a CW decoder and it will never work like what’s in between your ears. It really has a hard time decoding sloppy straight keys but extremely well with iambic decoding. It decodes straight key practice oscillator with precision sending. Most people use paddles or sticks anyway. This app is great for backup when I’m focused on a letter and now 14 letters behind and can jut glance over to catch up again. Apps absolutely worth the money. Maybe not the big app but this one is great. I’m extremely happy. Waaaay cheaper then a decoder on $15k radio that barely works and some commercial one that works poorly too. You shouldn’t regret it, (use manual settings) I don’t!
Straight Key,
QRP'ers Panadaptor
During the ARRL International DX contest I found it useful while operating QRP as I manually tuned looking for stations. The ability to rapidly and visually tune stations within the passband made for efficient operation and the capability to decode speeds beyond my own ability certainly helped to get some exchanges correct that might have otherwise been iffy. After the success I had, I purchased the pro-version, since I was happy to support Hot Paw's programming efforts and hope to encourage them to develop other high quality software for digital modes to include FSQ which is of interest here for emergency operations.
rhymeswithsilver,
You’ve tried the rest, now try the one that actually works
I tried a lot of the free and cheap CW decoder apps, but nothing worked or worked reliably. I bit the bullet on this $10 purchase and I’m glad I did.
I placed this next to a 60-meter radio with a poor signal, and this decoded the signal almost perfectly. 73, HotPaw!
The in-app documentation is a wall of text, but it’s easy enough to figure out on the fly.

The only working Morse decoder app
I'm not a fake review and this worked very well with my Icom IC-R8600 and RFSpace SDR receivers just using speaker output audio.
Set to fast rate and narrow filter and don't blast the signal if you have any noise or background static - watch the magic happen.
Great app for HF. Thanks app guy or lady. Enjoy the burger I bought you.

Newbie but learning,
Great app and great help to learn CW with instant feedback
Very pleased with this app and worth the price. I’m new to CW and this is helping to train my ears and finger coordination with instant feedback if my dits are correct. It really helped with my d,b,h,5,6. Thank for the app. Highly recommend.
Frozoloft,
Does not work!!
I had a clear morse signal, fully capable of being picked up by the iPhone's speakers. All it "translated" we're a few random letters over and over again. I tried every combination of settings on this app and I can tell you that this app absolutely DOES NOT WORK. The fact that I gave them nearly $10 for this garbage makes me even more angry. And they make a "Pro" version too? Wow. I'm going to report it to Apple even if I don't get a refund from them.
esmith512,
Holy crap! It actually works! Well!
I set the iPhone next to my receiver, fine-tuned it and set the notch filter on the app, and got complete readable copy, even through QRM. I usually expect a fight, this just worked right immediately.

Battlefield one help
Used the app to decode the Morse on battlefield one and it worked perfectly. So worth it!
timd441,
No work
No matter what settings I use on my iPhone X it will not work. I even used a known recording that was clear with no background noise and still only pick up a couple letters rest was trash needs updated for new phones wasted my $10
