Read full description

Morse Buddy is a live CW decoder for operators, listeners, and Morse enthusiasts who want more visibility into what a signal is doing in real time. Point your device at live audio and Morse Buddy runs four tuned ggmorse variants in parallel on the same signal. Instead of trusting a single decoder setup, you compare stock and enhanced processing side by side and see which view locks on best. Morse Buddy combines: - two stock ggmorse decoder variants - two enhanced ggmorse decoder variants - short-frame and long-frame behavior for different signal conditions - side-by-side live comparison in one focused 2×2 layout The enhanced panels show live frequency and confidence readouts so you can tell when a decoder is really on the tone. Whether you are experimenting with off-air audio, checking signal quality, or exploring Morse decoding on Apple devices, Morse Buddy gives you a fast, landscape-first interface built around live results. The display stays awake while the app is active so you can monitor without the screen dimming.
