Craving Toolkit is a privacy-first mobile app for craving and addiction recovery, designed for the moment a craving takes over and logic disappears. Unlike sobriety counters or recovery social networks, it leads with practical crisis tools: a 10-minute delay timer, guided urge surfing, breathing animations, counter-action, body-check exercises, and Voice of Truth — your own pre-recorded calm-state message played back when your triggered brain can't think straight. Everything runs locally in SQLite. No account creation, no analytics, no backend, no tracking. Companion app to the Craving Toolkit ebook (cravingtoolkit.com), based on lived experience and modern addiction science.
