PulseCode is an offline communication tool that lets you send, detect, and experiment with signals using light, sound, and local Wi‑Fi — all in one app. No internet? No problem. Communicate, test signals, or explore frequency-based interactions directly from your device. PulseCode brings three powerful channels together: **Light** Send and receive Morse-style signals using your camera, flash, or screen. Includes calibration tools, real-time indicators, and Light Watch to analyze brightness patterns. **Sound** Generate custom frequencies, build tone patterns, and run real-time signal detection. Test different frequency ranges, explore how sound interacts with your environment, and experiment with tones that may influence reactions such as movement or vibration in nearby objects or animals. **Local Wi‑Fi** Connect with nearby devices on the same network. Discover users, set a display name, and exchange messages directly — no internet required. --- **Privacy first** Core features work without any account or cloud connection. Permissions (camera, microphone, local network) are only used when you activate related features. --- Perfect for: • Outdoor and camping • Emergency situations • Signal experiments and learning • Offline communication
