Built by a hospital security supervisor who lost over 100 pounds working overnight shifts, it's coaching for people whose lives don't fit a textbook plan. Your coach learns from every workout, meal, and check-in, then adjusts your training and nutrition so the plan bends to you instead of the other way around. • A coach in your pocket — chat anytime and get real answers, not generic tips • Training that adapts to the equipment and the time you actually have • Effortless nutrition logging with barcode and photo capture • Apple Health sync for weight, workouts, sleep, and recovery • Progress tracking that shows how far you've come No crash diets, no shame — just a coach that shows up every day and meets you where you are.

The subscription auto-renews unless turned off at least 24 hours before the end of the current period; manage or cancel anytime in iOS Settings. Cancel before the trial ends and you won't be charged.
