Always there.

An AI coach that knows your workouts, your weight, and your goals. Ask a question, get an answer. Finish a session, it prepares the next one.

RepStack AI-powered workouts

All your fitness in one place

An AI coach that knows you

Talk to it like a real coach. It knows your past sessions, your weight, your goals. It advises you and programs your workouts.

Workouts, weight, activities

Strength training, cardio, yoga, swimming, body weight... all in one app. No more juggling between 3 apps.

Progress on autopilot

AI recap after every session. Weekly summary every Sunday. Smart auto-progression for the next workout.

How it works

1

Tell it who you are

Your equipment, goals, level. The coach adapts to you.

2

Train with AI

AI-generated sessions. Log your sets in one tap. The coach tracks your progress.

3

Talk to your coach

Ask a question, get advice, adjust your next session. It's always there.

C

The coach you always wanted

RepStack was born from walking into the gym with no plan. Not another logger. An AI coach that programs, tracks, and advises you, for the price of a coffee per month.
