10 Best Threesome Dating Apps: Try a 3Some on Swinger Sites

If you’re a couple looking for a third, or wanting to swing, then there are plenty of great swinger sites and threesome dating apps out there across the UK. Gone is the era when you had to look far and wide to find others with similar sexual appetites—these days all you have to do is find the right app for what you’re looking for. It makes life—and dating—a whole lot easier in 2026.

Below you’ll find a great list of apps if you’re looking for other UK swingers or are wanting a threesome.

1. AdultFriendFinder

This app/website tends to top the list when it comes to casual encounters of any kind. With nearly 100M users, you’re sure to find couples and individuals in the UK with the same sexual preferences you have. It’s definitively the largest naughty casual dating site out there.

A Social Network for Likeminded People

Adult Friend Finder is more than a threesome app, or swinger site—it’s an online community of people wishing to explore their sexual desires. In 2026, it feels more like a social networking site than a traditional dating site. For UK users, a full membership typically costs around £27.95 per month, with discounts for longer commitments.

The Best App for Variety

If you’re looking for online interactions as well as local UK hookups—whether to have a threesome, do swinging, or just have sexual encounters—AdultFriendFinder is a top option. A bonus is that you can sign up as a couple, or even a group.

2. Feeld

Feeld is a popular threesome dating app with a strong UK presence. It’s open to anyone looking for sexual encounters of the kinky kind, including swingers and those wanting a hookup.

Privacy and Gender

Feeld prides itself on being inclusive of those who don’t define themselves as straight, gay, or bi. Feeld usually requests a phone number or social login to help eliminate fake members. In 2026, the Majestic Membership in the UK costs approximately £14.99 for 30 days, or you can opt for a 90-day plan at around £29.99.

3. MW4M

This is a threesome website where you can create a profile if you’re a couple looking for a third, or a single person looking for a couple. It’s a useful alternative for those who prefer web-based platforms over mobile apps.

Not Just a Threesome Dating Site

In addition to helping you find your threesome, the site offers live model shows and member chats. While the interface feels a bit more traditional than some modern apps, it remains a consistent choice for the UK kinky community in 2026.

4. SwingerLifestyle

SwingerLifestyle acts as a social network for those looking to fulfill sexual fantasies. It’s a large online community where you can engage in group conversations as much as direct messaging.

A Swinger Site

The site is a popular choice for finding swingers near you in the UK. Most general dating apps are not dedicated strictly to swinging, so this is a great place to be if you want a platform that focuses specifically on that niche in 2026.

5. SDC

SDC, also known as Swingers Date Club, has been around since 1999. It remains one of the biggest swinger sites globally, including a very active UK membership base.

A Site for Couples

Over 50% of users on SDC are couples—including many LGBT+ couples. In 2026, SDC full membership for UK users is priced at approximately £22.95 for a single month, while a 12-month subscription averages out to about £9.16 per month.

6. Zever

Zever (formerly The Unicorn) is a site that focuses on the swinger lifestyle and finding threesomes in particular. It’s perfect for a UK couple looking for a third, or a "unicorn" looking for a couple.

App Emphasis

Beyond being a site for swingers, Zever focuses on creating a respectful community. They emphasize that consent and respect come first. While it hasn't got the massive membership base of the giants yet, its UK user count continues to grow in 2026.

7. FNTSY (Fantasy Match)

This threesome app is designed specifically for people in ethical, open, and polyamorous relationships. It is highly regarded by the UK poly community for fostering a respectful environment.

Nice Privacy Settings

All profiles are private by default, and you can adjust your settings to determine exactly who gets to see your profile, which is great for discretion in 2026.

8. 3Fun

3Fun is one of the most popular threesome dating apps in 2026. It has a high rating on the App Store and is a go-to for UK couples looking for a third.

Photos

You can have your profile photo verified for authenticity to ensure you are meeting real people. In 2026, the VIP subscription in the UK starts at approximately £24.99 per month, or around £39.99 for three months.

9. 3Way

Marketed as a location-based service, 3Way allows you to find people in your local UK area up for action without displaying your exact coordinates for safety.

A Threesome App or Swinger Site

3Way operates with more freedom regarding profile photos, including a feature to blur parts of photos for anonymity. It’s a solid choice for hookups of all kinds in 2026, including threesomes and swinging.

10. 3Somer

3Somer is an app entirely dedicated to threesomes. If that is your sole focus in 2026, this app is a direct and simple option.

No-Nonsense Experience

While it may have a smaller membership than AdultFriendFinder, all users are there for the same specific purpose. You can engage in video chatting if you prefer online interaction first. It is a no-nonsense app for the UK threesome scene in 2026.
