RepStack is in beta — all features are free

After months of development, RepStack is now available in open beta. And during this phase, all features are free — including those that will be reserved for the Pro plan.

What is RepStack?

RepStack is a workout app with a real built-in AI coach. Not just a notebook where you log your sets. A tool that programs your sessions based on your equipment, goals, and training history.

Tell it what you have (home gym, full gym, bodyweight), what you want to train, and it generates an adapted session. During your workout, you log sets with a single tap. After, the AI analyzes your performance and gives you a personalized recap.

Why it’s different

Most workout apps are glorified notebooks. You build your own program, log your sets, end of story. Useful, but they never tell you what to do next.

RepStack fills that gap. The AI doesn’t just store your data — it uses it to program your next session. No more thinking about which exercises, what weight, how many reps. You open the app, your session is ready.

What’s included during beta

Everything. No limited free plan, no paywall. During beta, you get access to:

• Unlimited AI session generation — normally reserved for the Pro plan
• Detailed AI recap after every session with goals for the next one
• 873 exercises with images and muscle/equipment filters
• Unlimited custom exercises
• Full history of all your sessions
• French and English support

Why free?

Because we need your feedback. RepStack is built by a lifter, for lifters. Every bug you report, every feature you request, makes the app better for everyone.

In exchange for your feedback during beta, you get everything for free. Fair deal.
