Workout dating.
Real rooms. Real people.

The Codex Circle is a ClassPass-style workout-dating community inside thecodex.world. Spend the Codex Credits you already have, book a class at a partner studio, and meet someone who moves the way you do. No swiping. No pre-class chat. Just the workout.

Apply to join How it works

Already a Codex member? Apply with your existing email — same wallet, same credits.

Two ways in

Both modes spend credits. Both feed SmartBalance. You pick what fits.

Mode A — Match first

Get paired with someone compatible each week. Mutual interest unlocks a shared session picker — pick a class together, both wallets are deducted, location released 24 hours before the workout.

Mode B — Studio first

Pick the workout you want. SmartBalance quietly checks for a compatible member also attending. If a match is there, you both get notified. If not, you still get a great class — that's the whole point.

Frequently asked

Everything you'd want to know before applying.

What is The Codex Circle?
The Codex Circle is an invite-only workout-dating community living inside thecodex.world. Members spend Codex Credits to book workout dates at partner studios in Lisbon and Dubai. SmartBalance routes a balanced mix of people to each session so the energy in the room is right.
How is this different from a dating app?
There is no chat before the workout. You book a real class, you show up in person, and connection — if it happens — happens face to face. The class itself has value whether or not you meet someone.
Do I need a Codex account?
Yes. The Circle uses the same login and the same Codex Wallet you already have at thecodex.world. If you don't have an account, you'll create one during the apply flow.
How much does a session cost?
Studios set their own credit rate — typically 3–8 credits per session (1 credit = €2). Reformer Pilates classes sit around 8 credits; run clubs around 3 credits. Codex retains a 15% platform fee on every Circle booking.
Which cities are live?
Lisbon and Dubai are the v1 launch cities. Other European cities open as studio density crosses the threshold — register your interest at /circle/apply.
How does SmartBalance work?
Studios set a target gender ratio for each Circle session. SmartBalance routes members so that ratio fills naturally — invisibly, in the background. Members never see the mechanic, only the recommendation.
Is it really invite-only?
Yes. The Circle is gated on application to keep quality and intent high. Apply at /circle/apply — most applications are reviewed within 48 hours.
