Signal Atlas

Signal Atlas is an offline sci-fi radio signal atlas for curious explorers.

Tune into distant beacons, satellites, stations, emergency calls and unexplained anomalies from a fictional universe. Every transmission is presented as a living visual waveform with its own source, sector, distance, reliability and hidden story.

Use the Scanner to discover active and nearby signals, then decode message fragments one by one. Explore transmission analysis, source records, reception timelines, related signals and field notes from past researchers.

The Archive lets you search through a collection of intercepted transmissions by name, sector or message. Filter signals by type, sort them by strength or rarity, and uncover the quiet corners of the spectrum.

Save remarkable discoveries to your personal archive and revisit them whenever you want. Signal Atlas works entirely offline: all signals, stories and settings stay on your device.
