    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.

    Sleep-supporting dinner foods: salmon, sweet potatoes, tart cherries.
