SFIT - Workout & Personal App
Student & Trainer Workout Gym
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Built for those who train and those who train others. Create personalized workouts with AI, manage clients, and track progress—all in one place.
Guided training, measurable progress, and a better connection between athletes and personal trainers.
S-FIT brings workout planning, execution, and progress tracking together in one place. Train with more structure and consistency as an athlete, or manage workouts and track your clients’ progress as a personal trainer.
For athletes:
• Personalized workouts: access your training plans with exercises, sets, reps, weights, and rest intervals.
• Interactive workouts: log every set, adjust reps and weights, pause and resume sessions, swap equivalent exercises, add extra exercises, and leave notes.
• Cardio tracking: record running, walking, rowing, cycling, and other activities alongside your strength workouts.
• S-FIT Personal: get AI-powered support throughout your training. Ask questions about your current session or overall progress, analyze your latest sets, compare performance, get suggestions for weight and rest adjustments, receive technique guidance, and discover your next steps. Any suggestion that modifies your workout requires your confirmation.
• AI-powered workout creation: build personalized workouts through a guided conversation with S-FIT Personal. Choose between a single workout or a complete weekly training plan, then review and adjust each exercise.
• AI with control: use AI-powered workouts and recommendations when you choose. S-FIT requests specific consent before sharing data and lets you revoke that permission at any time.
• Progress tracking: follow your workout history, sets, reps, training volume, duration, attendance, weekly goals, reports, and body measurements.
• Apple Watch: continue your workout from your wrist and track exercises, sets, rest intervals, heart rate, and active energy, synchronized with your iPhone.
• Live Activities and widgets: keep track of your workout and rest intervals without opening the app.
• Exercise library: explore 1,000+ exercises with instructions, muscle groups, equipment, and alternatives, or create your own custom exercises.
For personal trainers:
• Client management: organize clients, invitations, trainer-client connections, and progress data in one place.
• Workout creation: build personalized training plans from the exercise library, customize sets, reps, weights, rest intervals, equipment, and exercise alternatives, or use AI to streamline your workflow.
• Client tracking: review completed workouts, training frequency, progress, body measurements, and workout change requests.
• Plans and subscriptions: choose the plan that fits your needs and restore or manage your subscription directly in the app.
• S-FIT turns every workout into a measurable step forward—with better tools for personal trainers and greater clarity for athletes.
