Best Apps for Couples Looking for a Unicorn and How to Do It Right
The best apps for couples looking for a unicorn are the ones where both partners are verified, the couple has one profile and the woman you want to meet controls who can contact her. That rules out most mainstream dating apps. Below is how the main options compare, why many couples fail at unicorn hunting, and what the couples who succeed do differently.
Which app is best for couples looking for a unicorn?
For a couple, the best fit is a lifestyle app with a real couple profile and verification on both sides. Sinners checks every member with an ID and live selfie, shows boundaries before chat and lets singles restrict who writes to them. Feeld and 3Fun have bigger pools but weaker verification, and Tinder or Hinge do not support couples.
What unicorn hunting means, and why the word is loaded
A unicorn is a single bisexual woman who joins a couple for a threesome. Unicorn hunting is the couple's search for her. In polyamory and swinger circles the phrase has a bad reputation, because it often describes couples who treat the third as an accessory: a rigid rulebook, no say for her and an expectation that she will leave when the novelty does.
Most of the women you want to meet know this. Many have been burned by a couple whose second partner turned out not to be on board. If you start with that understanding, you stop competing on charm and start competing on trust, which is what a verified app is for.

Why most couples fail at unicorn hunting
One partner is keen and the other is polite
This is the biggest reason a third leaves. If one partner is quietly unsure, the single feels it within one date. Agree out loud, both of you, that you want this and what happens if either of you wants to stop.
A rulebook with no room for her
Rules like no kissing or no overnight stays are fine if they come from your real limits. They fail when they are written to protect the couple from the third. Keep your list short, honest and the same for her as for you.
Treating the search as casting
Profiles that list exact looks, age and body requirements get ignored. Describe who you are and what the evening could look like, not the product you are shopping for.
Moving too fast or too slow
A week of chat, a drink, then an honest conversation on the way home works for most people. A month of messages usually ends in silence.
What a verified app changes for the woman you want to meet
She sees that both partners exist and passed an ID and selfie check. She sees your boundaries before replying, so she knows whether you are open to a kiss, a dinner or a night. She can choose who may contact her, keep her photos blurred and unlock them for you only after she has talked to you. For her, that is the difference between a couple she can trust and a profile she has to question.
For you, it means fewer dead ends. The replies you get come from people who already understand what you are and are comfortable with it. Use the boundary match to show where you overlap, and read how to word the first message in our guide on how to find a third.
What to do before you start
Talk about what a third means for the two of you beyond the fantasy. The agreements in our open relationship rules guide are a good starting point. Pick a profile photo you are both happy with that does not show your face if you are not out. Treat the first drink like a date night, and if it goes well, some couples like to have silk robes ready for the evening after. Keep the first meeting itself short and in public.
What it costs to look for a unicorn on Sinners
Couples is 59 USD per month for both partners, or 29 USD per month billed yearly. Elite is 99 USD per month and adds incognito browsing and travel mode.

Unicorn hunting questions
What is the best app for couples looking for a unicorn?
The best app has a real couple profile, verification for both partners and tools that let the single control contact. Sinners offers all three. Feeld and 3Fun have larger pools but verification is optional, and Tinder and Hinge do not allow couple profiles.
Is unicorn hunting bad?
It can be. The phrase describes a pattern where a couple treats a third as an extra and sets rules only for her. Couples who write honest profiles, share the same limits with her as they have for themselves and respect a no do far better, and are the ones singles reply to.
How do couples find a unicorn safely?
Use an app that verifies both partners, meet for a short drink in a public place, keep real names and addresses private until trust is built and tell a friend where you are. Agree beforehand on a signal that ends the night.
Where do couples find a unicorn near me?
On lifestyle apps with a location search, at swinger parties and at hosted events. Search by distance and boundaries. On Sinners you filter single women near you and see what each is open to before you write.
Why do unicorns leave couples?
Common reasons are one partner not being fully on board, rules that apply only to her and a couple that expects more time than she wants to give. Being clear at the start and checking in after each meeting reduces it.
