"The VOC calculator saved me from launching a major sigil during a 14-hour void period. Lunar Phase app added the ritual timer and journal — now I only launch during applying aspects. My success rate jumped from ~30% to ~70%."
VOC awareness is the foundation. The Lunar Phase Calculator Android app gives you: real-time Moon phase/illumination, ritual timer with planetary hour alerts, lunar journal with photo/audio notes, planetary hour calculator, and daily VOC alerts via Android notifications — all offline.
