The Circle

Stop swiping. Start meeting.

The Codex Circle is workout dating done right. You meet potential partners — or new friends — through a real class, not a profile. Here's exactly how it works.

Two ways to use it

Pick the one that fits your week.

For the intentional

Mode A — Match first

A weekly queue of three suggested matches. Mutual interest unlocks a shared class picker. One taps confirm — you both show up.

For the spontaneous

Mode B — Studio first

Browse Circle-visible classes in your city. Book solo. If a compatible attendee is there, you'll both be told. If not, you still got the workout.

Why we killed pre-class chat

Texting before meeting is what breaks dating apps. People over-invest, build a parasocial sketch of someone they've never met, and the real meeting under-delivers. The Circle removes that step by design.

You see one face across a class. You feel chemistry — or you don't. 48 hours later, you each get a single prompt: did something spark? Mutual yes opens the conversation. That's it.

Common questions

What is workout dating?
Workout dating is meeting a potential partner — or new friend — through a shared real-life class instead of through a profile and chat. The Codex Circle is the platform that runs it across Lisbon and Dubai: you book a real session at a partner studio, the SmartBalance engine quietly fills the room with compatible people, and you connect in person.
How does The Codex Circle work?
Apply to join (free, invite-only, reviewed in 48 hours). Top up Codex Credits. Book a class — Pilates, yoga, run club, boxing, or strength. SmartBalance curates who's in the room. You meet at the studio. 48 hours later, both members get a 'something sparked?' prompt — mutual yes opens messaging.
Where is workout dating available?
The Codex Circle is currently live in Lisbon, Portugal and Dubai, UAE, with city waitlists open in Paris, London, Madrid, Barcelona, Amsterdam, Berlin, Milan and New York. Founding members get permanent perks when their city launches.
Is The Codex Circle free?
Yes — membership is free. You only pay for the classes you book, using Codex Credits (1 credit = €2). Typical class: 3–8 credits. Top up in bulk to save up to 20%.
Is it really invite-only?
Yes. Every application is reviewed by a human, usually within 48 hours. The gate exists to keep the room high-intent: people who actually train, actually show up, and actually want to meet someone.
What is SmartBalance?
SmartBalance is the matching engine that quietly curates each Circle class. It balances gender ratio, mode (dating or friendship), orientation and compatibility, so the room always works. Members never see the mechanic — only the result.
How much does a session cost?
Studios set their own rate. Typical range: 3 credits (€6) for a run club, 5 (€10) for yoga, 6 (€12) for boxing, 8 (€16) for reformer Pilates. 1 credit = €2.
When are credits charged?
Credits leave your wallet when you confirm a booking. They're held until 24 hours after the class so you're protected by the cancellation rules.
Can I cancel?
Cancel 24+ hours before: full refund. Under 24 hours: 50% refund. No-show: no refund and a flag on your account. Three flags removes you from The Circle — to protect the people who showed up.
When does messaging unlock?
48 hours after the class, you and any matched member get a single prompt: 'something sparked?' If you both tap yes, messaging opens. If not, the connection closes cleanly — no awkward back-and-forth.
Is my location shared?
The studio address is released to confirmed bookings 24 hours before the class. Member-to-member location is never shared.
Can I use The Circle for friendship, not dating?
Yes. Set your mode (dating, friendship, or both) and orientation in your profile. SmartBalance respects both.
How is this different from Hinge, Bumble or Tinder?
Different category. Dating apps are good at discovery and weak at meeting. The Codex Circle skips the chat: you meet in real life first, in a room full of people who already share your training habits. No swiping, no pre-meeting texting, no parasocial sketch of someone you've never met.

Who The Circle is for

If two of these sound like you, you'll probably love it.

  • You train 3+ times a week and meet most of your friends through that.
  • You're done with swiping but not done with dating.
  • You'd rather show up to one class than send 40 texts.
  • You want to make new friends after moving to Lisbon or Dubai.
