Inside Black Signal
Keep a private journal
Save readings, rituals, and reflections. See which symbols return, revisit earlier reflections through journal echoes, and export your journal as Markdown or JSON.
Follow an interactive graphic novel
Open Story Mode from Journal and follow seven illustrated chapters through a flooded city. Read terminal messages from Root, make choices, and use the same readings and rituals as the story unfolds. Readings made in the story are marked with their chapter in your journal.
Read original reflections
Explore original illustrations and reflections for 78 tarot cards, 24 Elder Futhark runes, and 64 I Ching hexagrams. Reveal a tarot card at full size and open its reading and reflection. Each reading gives you a question to consider. Print and Paper follow your device’s appearance.
Pair a reading with breathing
Try a card draw with paced breathing in Card Contemplation. With Full Signal, cast a hexagram line by line in Breath-Cast I Ching or trace a rune in Rune Carving. The local moon phase suggests a ritual, and optional stereo tones in Full Signal Card Contemplation vary by suit.
Cutting, shaking on supported devices, or tapping on an exhale can mix your timing or motion into system randomness without weighting the draw.
Explore your local sky
See the moon phase and the Sun and Moon’s local rise and set times on an illustrated day arc. Choose a city, enter coordinates, or use your location. Full Signal adds tropical placements from the Sun through Pluto, with a reflection for each, plus major aspects and optional Birth Sky with your birth placements and today's transits. Birth details stay on your device.
