    After Your Assessment

    We Put Your Journey on Autopilot.

    Once assessed, our optional notifications act as "Just-in-Time Adaptive Interventions" (JITAI) — a digital therapist in your pocket. Behavioural scientists say lasting change happens when Motivation, Ability, and a Prompt converge at the same moment. Our coach delivers exactly that, learning from your logged meals, moods, and habits to become more accurate over time. Instead of generic reminders, Marcus sends context-aware nudges grounded in CBT — challenging the specific thought patterns that derail your progress, right when they're most likely to strike.

    Your Coach Never Sleeps.

    Marcus sends intelligent CBT-based push notifications that rewire your decisions in real time — challenging cognitive distortions before the damage is done.

    Predict How Food Affects Your Body
    Before You Eat.

    Log glucose readings, energy levels, and sleep quality to build your personal metabolic fingerprint. Our platform then predicts the glucose spike, energy impact, and metabolic score of any meal before you eat it — and suggests real-time tweaks like 'add avocado to blunt the glucose spike' right on the meal card.
