Predict. Prepare. Prevail. NeuroCurve™ brings tracking and reflection together for everyday self-management of habits and compulsive patterns, including responses associated with OCD and scrupulosity. Name a response you want to understand, such as repeated checking or reassurance seeking. Record selected sessions, explore your NeuroChart™, and consider your next step. You can also use NeuroCurve for everyday habits such as scrolling. OCD AND SCRUPULOSITY Scrupulosity involves religious or moral obsessions. NeuroCurve focuses on your response patterns. It does not judge your beliefs, measure your character, or determine whether an intrusive thought is true. Use tracking alongside guidance from a qualified mental health professional. You do not need to record every thought or check the app for certainty. If checking the timer, chart, or AI replies becomes part of a ritual, pause and discuss your use with your clinician. WHAT YOU CAN DO • Track selected responses Start a session and record when you act on the urge. Save & Restart begins the next interval. Stop for today pauses tracking while keeping your saved history and urge name. • See your NeuroChart Review recorded sessions and changes in your response pattern. After at least three completed sessions, the app can begin estimating a next likely response window from your recorded activity. • Reflect with NeuroCoach™ Use AI-powered conversation for general reflection and encouragement. Listen to replies or save useful responses to Coach Notes. NeuroCoach is not a therapist or a source of religious or moral certainty. • Choose optional reminders Set reminders and preparation alerts to fit your routine. • Review and share Return to earlier sessions and choose what progress to share. Support Circle offers a place for encouragement from people you invite. UNDERSTANDING THE ESTIMATES The NeuroCurve Model™ uses your session timing and intervals to estimate patterns. Estimates may change as you record more sessions. They do not predict intrusive thoughts, guarantee when an urge will occur, or establish clinical improvement. NeuroCurve is a self-management and educational tool. It does not diagnose or treat OCD or any other condition, provide guided exposure and response prevention (ERP), or replace professional care. AI responses may be inaccurate. SUBSCRIPTION ACCESS A monthly or yearly subscription is required for the main tracking and NeuroCoach features. There is no free trial.
