Triple Hearts

Opening soon · join the waitlist

Everyone knows.
That's the point.

A dating app for adults in ethically non-monogamous relationships — where dating more than one person happens with everyone's knowledge and agreement. We match on the two things that actually decide whether it works: when you're free, and what you've already agreed with the people you love.

One email when we open. Nothing else, ever — and no tracking pixels on this page.

A compatibility report, roughly

Tuesday and Thursday, you're both free. That's where this starts.

You both keep Sundays for a nesting partner. Neither of you has to explain that.

You want overnights. They've agreed not to, for now. Better to know on day one.

86

out of 100 — mostly because your weeks fit

Two or three people, ordinary and unposed — a kitchen, a walk, a bar. Not a stock couple.
One person alone, relaxed, mid-thirties.
A group at a table, laughing, phones away.

Let's be direct about it

People assume they know what this is. They're usually wrong.

What it is

A relationship app for people who date more than one person openly. The defining feature is disclosure — everyone involved knows, and has agreed. That is the entire distinction.

What it isn't

An adult app. There is no nudity, nothing sexually explicit, and no services offered or solicited anywhere in it. Our photo rules are no looser than any mainstream dating app's.

The name

Three hearts, because a relationship network is more than two people. It isn't a reference to a sexual act, and we'd rather say so plainly than let anyone guess.

Writing about us? The plain-language explanation lives on the safety and standards page.

How the matching works

Chemistry isn't the hard part. Calendars are.

Most dating apps ask what you like. That's not what makes a second or third relationship work. During signup you answer four sets of questions, and we compare your answers to someone else's honestly — including where you don't line up.

01 · Your week

Which evenings are actually free, and which are already someone else's. Two people who both keep Sundays for a nesting partner are compatible in a way a quiz can't guess.

02 · Your agreements

What you've already settled with existing partners — overnights, disclosure, how many nights out. Comparable answers, so a conflict shows up as a conflict.

03 · Your structure

How you date now and what you're looking for. Nobody has to explain the basics of their own life in a first message.

04 · Your differences

We show where you don't line up, in the same report, with the same weight. A match that hides the hard part isn't a match.

The podcast · Four Sundays

Long conversations with people about how they actually organise their relationships. No experts, no advice — just the logistics nobody talks about.

Live events · Rooms, not apps

Small mixers and workshops in six cities. Vetted guest lists, a code of conduct read out loud, and no photography without asking.
