The challenge
People training at the gym want to log every set without losing pace, see real progress and not depend on their phone between sets.
The solution
Live workouts with rest time in the Dynamic Island, an Apple Watch app synced with the iPhone, progress charts with estimated 1RM, and an AI agent that creates and schedules routines, nutrition plans and habits from a conversation.
Under the hood
The AI agent uses tools to act inside the app: it creates routines, schedules workouts, logs meals and navigates screens. Local data with SwiftData, watch sync and full Spanish and English localization with String Catalogs.
