AI Diet Coach is your personal AI trainer for diet and exercise—guiding you all the way to your weight-loss goals.
■ Your own AI trainer
Choose a trainer with a personality that fits you. Chat anytime about food and workouts, and your bond grows the more you keep going.
■ See what to do today, at a glance
A simple daily checklist keeps your meals and exercise on track. No overthinking—just start with what you can do.
■ Meal & workout plans, made for you
Get realistic diet and exercise plans matched to your goals and preferences. Not a fan of exercise? We won't push hard workouts on you.
■ Log by just chatting
Say "had pasta for lunch" or "walked for 30 minutes" and it's logged. Weight and steps sync automatically from Apple Health.
■ Watch your progress grow
At every milestone, your AI writes a "progress report" reflecting on your effort—remembering your long-term journey to coach you better.
Free to start. Richer support is available with a paid plan.
