Cathexis
Your private companion for managing panic attacks with science-based techniques—built for when you need immediate support.
Your Private Panic Attack Companion
Cathexis is a mental health app designed specifically for people experiencing panic attacks and acute anxiety. With a panic-first design philosophy, the app provides instant access to proven grounding techniques, breathing exercises, truth cards, and SOS mode—tools that help you regain control during overwhelming moments.
