Use them together, as Budy does, or one at a time. Each engine works from the person’s own goals, schedule, health context, and history.
Workout planning
Multi-week plans from goals, training days, session length, equipment, experience, and health notes, drawn from a library of more than 4,800 exercises.
Adaptive training
Plans adjust to logged sets, workout feedback, missed sessions, sleep, and changes of equipment or location, with exercise swaps that keep the plan’s intent.
Equipment recognition
Identifies each piece of gear in a photo of a gym, so a plan only uses what is really there.
Nutrition and meal planning
Calorie and macro targets, a daily food schedule, and meal suggestions around diet style, allergies, cuisines, and training days.
Meal photo analysis
Estimates calories, protein, carbs, and fat from a photo of a meal and adds them to the day’s progress.
Supplement assessment
An AI review of what to consider taking, with fixed safety rules for allergies, pregnancy, medicines, and duplicates applied before and after the AI answers.
Biological age
Reads a blood test report and calculates PhenoAge from nine blood markers, a published biological-age measure. The user checks every value before it is saved.
Body composition and fitness age
Reads InBody-style body scan sheets for muscle and fat, and estimates fitness age with or without a watch.
AI coach
A chat coach that knows the plan, recent workouts, and meals, and can offer a plan update for the user to review.
Voice-guided workouts
Spoken cues for each exercise, rest period, and transition, so people can train without watching the screen.
Health data and insights
Takes in workouts, steps, heart rate, sleep, and weight from Apple Health and Health Connect, and turns training into strength, volume, and personal-record trends.
Engagement
XP, streaks, quests, badges, leaderboards, and training partners that help people keep showing up.
