Morse Pad is a handy iPhone app developed by Black Cat Systems that allows you to monitor and decode Morse code transmissions on your device. With this app, you can easily tune in to a Morse code transmission using your iPhone, iPad, or iPod Touch, and watch as the text is decoded right in front of you.

One of the key features of Morse Pad is the ability to input the Morse code speed in Words Per Minute (WPM). Alternatively, you can enable the Auto WPM mode, which automatically determines the sending speed. Please note that it may take a moment for the app to determine the speed or adjust to changes in speed.

To ensure accurate decoding, Morse Pad also requires you to enter the center frequency of the Morse code audio in Hertz (Hz). The app offers an Automatic Frequency Control (AFC) option, which allows it to track frequency changes and lock onto the strongest signal available.

In addition, Morse Pad provides a spectrum display in the upper left corner, showing the audio spectrum with a red line indicating the center frequency. This feature can be used as a tuning aid to further enhance your decoding experience.
