THE IN-RACK COCKPIT · GYM MODE
Zero guesswork in the rack.
One progression engine parses the sets you actually log — experience-scaled starts, a weight-up call after a full session, a hold when you cut sets short, and a joint-flag deload when something hurts. An estimate is labeled an estimate until your logged sets replace it.
Gym Mode is part of Local+ ($4.99/mo). Free Mode logs your sets free today — no card, no account.

Questions
Why no wearable or app integrations?
Because clean signal beats more signal. Eccentryx coaches on what you actually did under the bar — the load you moved and the effort you reported. Manual logging forces intention; integrations would import data you did not choose and could not verify. Your logbook is the ground truth, and we keep it that way.
Is Eccentryx really free?
Yes — Free Mode, the Atlas, and the public tools are free today with no card and no account. Local+ ($4.99/mo) and Pro ($9.99/mo) are optional subscriptions billed securely through Stripe, cancel anytime.
Where does my data live?
In your browser first — local-first is the default, and you can export or erase everything anytime. Signing in is only needed to subscribe or to opt into encrypted account-based cloud sync (eligible Local+ and Pro), which is optional and never required for the free tools.
