About PulseCode

PulseCode is an offline communication tool to send, detect, and experiment with signals using light, sound, and local Wi‑Fi — all in one app. Test signals and explore frequency-based interactions directly from your device.

Light — Morse-style signals with camera, flash, or screen; calibration, real-time indicators, and Light Watch for brightness patterns.

Sound — Custom frequencies, tone patterns, and real-time detection. Explore how sound interacts with your environment.

Local Wi‑Fi — Discover nearby devices on the same network, set a display name, and exchange messages — no public internet required.
