Your nervous system is doing something right now. Tightness somewhere. A hum of energy. A heaviness you've learned to ignore. Cathexis starts there — with what your body is actually telling you — and builds outward. Cathexis is a somatic therapy tool grounded in seven neuroscience frameworks: how your brain constructs emotions from body signals, how it predicts and updates predictions, what drives your motivations, how body states shape decisions, how the whole brain coordinates emotion, how unconscious patterns surface, and how memory can be rewritten through practice. YOUR BODY, MAPPED Each session begins with a body check-in: where you feel sensation, what quality it has, how intense it is. Tag your context — energy, location, what's happening — and over time, patterns emerge that your nervous system has been running without you noticing. With your permission, Cathexis integrates with Apple Health, your calendar, motion activity, weather, location, and Health Records (FHIR) — building a picture of what your body does in the context of your life. All data stays on device. NINE 30-DAY THERAPEUTIC PROGRAMS Each addresses a specific way your nervous system learned to protect you: • Living with Threat — anxiety, hypervigilance, panic • Living with Shutdown — low mood, numbness, fatigue • Living with Loss — grief, yearning, hollowness • For Those Who Feel Too Much — flooding, overwhelm • Living Under Siege — when the past keeps intruding on the present • Living with Conflict — being torn between opposing truths • Living in the Body Under Strain — chronic pain, body image, disordered eating • Living Under Pressure — burnout, chronic stress, system exhaustion • Navigating Change — identity shifts, life transitions Six learning levels per program — from guided body awareness to independent practice. FOUR FREE REGULATION PRACTICES Extended Exhale, Five Senses Grounding, Foundation Body Scan, and Box Breathing — always available, no subscription required. TWO FREE CRISIS-RESPONSIVE PROGRAMS Still Here — a 7-day somatic safety practice for when staying feels difficult. Builds a personal Somatic Safety Plan. New Ground — a 7-day practice for when your world changed without warning. Builds a personal Somatic Crossing Map. Both free. No trial, no limits. Verified resources for crisis, self-harm, eating disorders, substance use, domestic violence, and sexual assault are always accessible. ON-DEVICE INTELLIGENCE AI runs entirely on your iPhone using Apple's on-device models — your data never leaves your phone. Your somatic field — built on reaction-diffusion mathematics — visualizes your nervous system in real time. During practice, it breathes with you. Ask it questions by voice or text and receive observations grounded in your own data. Morning predictions and evening check-backs help your brain update its patterns. Substance use and medication logging help your patterns make sense. Siri Shortcuts let you check in, start a practice, or get a somatic summary by voice. BUILT FOR YOUR PROVIDER A Session Report PDF captures your patterns and practice data in clinical language — ready for any provider. Your Treatment Plan is a living summary you own. My Story builds a portrait of your experience over time. INSIGHTS Three views: brain network activation, body sensation mapping, and the connections between your internal systems. Regulation trends, somatic trajectories, and prediction accuracy track what's changing. Monthly Reflections generate ongoing narratives as you progress. PRIVACY AS ARCHITECTURE Everything on-device. Nothing uploaded. Full data deletion anytime. A local Model Context Protocol (MCP) server lets external AI tools access your data with explicit permission at four granularity levels. BUILT BY A CLINICIAN Designed and built by a licensed therapist in residential treatment. Every practice, every word, every safety threshold reflects direct clinical experience with these patterns.
