CoachArc

CoachArc is an AI fitness coach that reacts to your data instead of asking you to fill in a form every week.

Upload a DEXA or InBody scan, connect a wearable, log your sets, or miss a week entirely — CoachArc reads what actually happened and reworks your training block and food guidance around it. A scan showing lost lean mass changes your working sets. A poor recovery trend eases the day. A missed week rebuilds the plan from where you actually are, not where the template said you would be.

Two things it deliberately does not do. It never changes your week silently — every adjustment is proposed and waits for your approval before anything moves. And it stays in its lane on health: bloodwork is read for the training or nutrition lever it points at, never interpreted as a medical opinion, with anything clinical routed to your own provider.

Available on iPhone, with Android in closed testing. Subscription with a 30-day free trial.
