Want to monitor morse code transmissions, without using a bulky computer? Morse Pad lets you decode morse code on your iPad, iPhone, or iPod Touch. Just set your device near a radio, tune in a morse code transmission, and watch the decoded text.

Enter in the morse code speed in WPM. Or you can turn on Auto WPM mode, and Morse Pad will try to determine the sending speed. Note that it may take take a moment for the app to determine the speed, or to adjust to changes in speed.

You also need to enter the center frequency of the morse code audio, in Hz. Morse Pad has an AFC (Automatic Frequency Control) option, it will automatically track frequency changes and lock on to the strongest signal found.

The spectrum display in the upper left corner shows the audio spectrum, with a red line drawn over the center frequency. This can be used as a tuning aid.

Buy your copy of Morse Pad right now, and start decoding and displaying morse code transmissions in minutes.

It works,but it's terribly slow, lagging several letters behind. Given the speed of the processor in the iPad it should be much faster. Trying learned the screen while listening to the audio can be either confusing or annoying. But for under 3 bucks, it's acceptable.

Simple and works- worth the cost

Like the previous reviewer I was looking for a Morse decoder that could decode audio for a Battlefield 1 Easter egg. This worked beautifully. I didn't even have to adjust anything or toggle on the auto- features; it decoded the Morse very well.

Once I found that the RECORD feature saves a transcription of the decoding, this app became even easier to use. I'd let it run through 3 or 4 repetitions of the pattern and be able to eliminate errors easily. Highly recommend it.

Every once in a while (say 1/50) it would get a letter wrong but I blame that on the audio file also containing a lot of background noise like thunder, bird chirps or artillery.

I tried $0.99 Morse-it and it returned gibberish. And the $9.99 HotPaw seemed excellent but a little pricey given I just wanted it to unlock a puzzle in a video game.

So good job dev! Your app delivers its intended function very well and easily and the price point made it worth the gamble.

1-char buffer delay

I use this app to check on how well I’m sending. If I Send at 20 chars/sec. and my words per second are say 15 there a space between each character. It would be nice if there were two adjustments: chars/sec and words/sec.

Also: If I send hello the app displays hell. I need to send an additional char to flush out the receive buffer and then the “o” will display.

Add a clear screen display on the front otherwise you need to flip to the backside to clear.
