CoachArc is a fitness coach that pays attention. Upload a DEXA or body-composition scan and CoachArc does not just chart it - it shows you the specific training and food changes it wants to make because of what the scan says, and what it is protecting while it makes them. Upload a blood panel and it groups your markers - hormones, thyroid, inflammation, heart, nutrients, blood count, liver and kidney - and reads them next to how you have actually been training. It flags what is worth showing a provider. It never diagnoses. Connect Apple Health and it uses sleep and sleep stages, HRV trend, resting heart rate, steps and active calories to make one call a day: ease off, keep an eye on it, or stay quiet. On days when nothing has changed, it says nothing. WHAT ELSE IT DOES - Today tells you what to do - one clear next step, not a blank screen - Hey Coach answers questions grounded in your actual plan, history and schedule - Progression recommendations arrive with the reasoning shown: what you last lifted, what it wants next, and the rule behind the jump - Food guidance that shifts with your goal track and training demand - Classes count as real workouts, and rest days are open days - a walk or a class belongs there - Progress, body composition and lab history in one place YOU STAY IN CHARGE Every adjustment arrives as a proposal with what changed and why. Nothing is applied until you tap to accept it, and anything you accept, you can undo. CoachArc never rewrites your plan behind your back.
