What do I get free vs Pro?
No account: Last Stack (hardest AI, one stack, nothing saved), the trainer, and the tools — pot odds, equity, ICM, charts, light solver, variance. Free account: that work is saved, plus a rated Live ladder — day one is mostly labeled AI. Pro ($9.99/mo or $59.99/yr): Lightning (~25× a live table, ~750 hands/hr, coach on) and the HUD. You are not paying to unlock math.
Is this real-money gambling?
No. Play-money only. No chips to buy, nothing to cash out. Rank is a skill signal — never a casino.
Why not just use GTO Wizard?
Wizard is still the deepest encyclopedia. We don’t replace it. We sell the gym. Lookups here are free — light GTO, not a 100-million-spot library. Wizard Starter is about $49/mo to browse trees. Pro is $9.99 for volume and a coach on YOUR hands.
Can I cancel Pro anytime?
Yes. $9.99/mo or $59.99/yr. Cancel whenever. No lock-in. Play-money only.
