I’ve been testing this Morse Code from Audio app, and it does exactly what it promises—turning live audio signals into readable text in real time. It’s especially useful for anyone learning Morse code or working with radio/CW signals.
What impressed me most is the automatic frequency and speed detection. You don’t need to manually tune settings every time—the app intelligently locks onto the signal and starts decoding almost instantly. The real-time text output feels smooth and responsive, even with varying signal quality.
The interface is simple and focused, which makes it beginner-friendly but still powerful enough for ham radio enthusiasts. I also liked that it works directly from the microphone, so you can just place your phone near a speaker or radio and it starts decoding.
