Features
Everything you need to train smarter.
Tr.Ai.N combines a real coaching relationship with plans that adapt to your body, your gear, and your week.
16 AI trainer personalities
Some people need tough love. Some need patience. Choose from sixteen distinct coaches — each with their own style and voice — then customize yours to match exactly how you want to be coached.
Chat with your coach, anytime
Your trainer isn't a settings screen — it's a conversation. Ask questions, talk through a rough week, request changes, or just check in. Your coach remembers what you tell them and coaches you accordingly.
Plans that adapt automatically
Your trainer builds multi-week programs around your goals — and keeps adjusting them based on your available equipment, your time, your progress, and your recovery. Miss a session or crush one? The plan responds.
Guided workouts
A clean, distraction-free workout mode: exercise-by-exercise navigation, built-in rest timers, set-by-set tracking, and one-tap swaps when a movement isn't working for you.
1,300+ exercises with video demos
Every movement comes with a video demonstration so you know exactly what proper form looks like — from barbell lifts to bodyweight basics.
Works with Apple Health
Connect Apple Health and your training reflects your real life — sleep, activity, recovery. Completed workouts flow back to your health record. You control what's shared, always.
Progress you can see
Workout history, streaks, goals, and achievement milestones — the numbers that keep you honest and the wins that keep you going.
