Full history, not last session
Every set you ever log feeds the prescription. The engine sees plateaus, fatigue, and progress across months — not just today.
Training engine · Early access
Your next set is already decided.
Log a set in two taps and RepSetStat computes the next one: reps, load, and rest, drawn from your full training history instead of a static plan.
Prefer to start on paper? The training program is in the store as a print-ready PDF, with matching posters for the gym wall.
Digital downloads, delivered right after payment. The app itself is free during the beta — you sign in with Google, no password to remember.

Every set you log feeds the prescription for your next session.
What makes the engine different
Double progression, automated
Hit the top of your rep range and the engine adds load. Miss it and the engine holds. No spreadsheets, no guesswork.
Local-first, yours forever
Data lives on your device first. Export JSON anytime. Cloud sync is opt-in and paid — you stay in control.
Next: the bar that counts itself.
We are building a small sensor that clips onto a barbell or machine and counts reps straight into your history. It is optional and open hardware, and the engine treats a counted set exactly like a typed one: one more source, same data model.

The sensor is a later phase. Sign-ups get the app first; hardware news follows when there is something to test.
Questions, answered.
How do I start?
Create an account and you are in — the app is in beta. You sign in with Google, which is the only account you need; there is no separate password to set.
What do I need to run it?
A current browser on phone or desktop: Chrome, Edge, Firefox, or Safari. The app installs to your home screen as a PWA and works offline. Older browsers are not supported; that is a deliberate trade to build on one modern stack.
Where does my training data live?
On your device. Everything is stored locally first, and you can export a complete JSON backup at any time. Signing in is what will make cross-device sync possible — that work is next — and your local history carries over rather than being replaced by it.
What will it cost?
Pricing is not set yet. Core tracking is free through the beta, and the app will tell you before anything changes.
What is the sensor?
A small open-hardware rep counter that clips onto a barbell or machine and logs reps into your history automatically. Everything works fully without it.
Ready to train on paper first?
The print-ready PDF program and gym posters are in the store — buy once, own forever.

Take the program with you from the store, or create your account and let the engine take it from there: log a set, get the next one.
