WannaHookUp is the newest open relationship dating app on the list, and it shows in every detail: the interface of the site looks more modern than the competitors, and the app is incredibly intuitive and easy to use. What we liked most about WannaHookUp during our test was the quality of the profiles—they are not verified by ID, unfortunately, but other than that, they look very real and detailed, with at least 3-5 photos and a lot of personal information.
Key Features: Convenient live chat, well-optimized mobile website
WannaHookup
OneNightFriend is a dating platform with one significant advantage: unlike other apps, it actually allows users to chat for free. Every user can send 5 free messages per day—it’s unlikely that you’ll find somebody and ask them on a date in just 5 messages, but it’s 5 messages more than the competitors offer. If you purchase a premium subscription, it’ll be much easier for you—premium users can boost their profiles, they can send multiple messages (Flirtcasts), enjoy advanced search filters, and so on.
Key Features: Flirtcast, profile boost, free messages
OneNightFriend
Adult Friend Finder is the oldest dating app on this list, and it’s not just old. In fact, it’s also one of the most popular and trustworthy adult dating platforms with more than 12 million monthly visits, and the quality of profiles is also pretty high here. It’s not perfect; there are no perfect dating apps with millions of verified and detailed profiles, but AFF is very close to this title because thousands of profiles here are verified by ID and have 5+ photos. AFF is also perfectly convenient for mobile users because it has very polished Android and iOS apps.
Key Features: Live streams, ID verification, chat rooms
AdultFriendFinder
With more than 3 million monthly visitors, TopLocalSingles is one of the largest apps for someone looking for a hook-up or for an open relationship. It’s a very simple site with a user-friendly interface, and that’s why, in our opinion, it’s one of the best options for beginners. But experienced open relationship enthusiasts will find something interesting here, too, because TopLocalSingles has a lot of detailed female profiles and a high reply rate (55%+).
Key Features: Live chat, mobile website
TopLocalSingles
BeNaughty doesn’t stand out from the crowd, to be honest—it offers a standard set of features (search tool, live chat, stickers) and the quality of profiles here is good but not perfect. It’s a decent, solid dating app that can work great for those who want to have fun—it has thousands of real users, most users here are looking for a casual hookup, and the app is very convenient and easy to use. It’s not that cheap, though: there’s a 3-day trial for only $0.99, but a subscription costs around $62 for three months.
Key Features: Chat rooms, user-friendly interface, simple search tool
Be Naughty
Ashley Madison is probably the #1 dating app for open relationships that comes to mind when you think about it. It’s popular, it has a very large userbase (75 million users, as they say), and it’s been trustworthy for years (at least since 2015). ID verification, mobile app, detailed profiles, and a good reputation—Ashley Madison is probably the top one night stand website right now.
Another interesting feature of this app is its focus on discreet dating—that’s probably not what you need in an open relationship, but in case you do, Ashley Madison allows you to change the app icon (the feature is called Stealth). The only problem is the cost: there are no free/welcome trial offers for new members here, unfortunately.
Key Features: ID verification, Stealth, Prime membership
AshleyMadison
These 6 platforms are the best dating sites for open relationships in 2025—we’ve tested each of them for at least 7 days, and we can say with confidence that these websites are trustworthy and reputable. It’s up to you which one to choose: if you want a large dating pool and lots of features, try Ashley Madison and Adult Friend Finder; if you want to chat for free, start with OneNightFriend; if you want a simple, user-friendly dating app with a high reply rate, you should focus on WannaHookUp and TopLocalSingles.
Read the reviews and test the sites—this can be pretty time-consuming, but that’s the only way to find the top dating apps with the best reputation. And always pay extra attention to the quality of profiles: if they’re verified and detailed (have at least 2-3 photos), it’s a green flag.
Well, no, typically, they don’t. However, they are not the best choice for someone looking for open relationships: most members there are not looking for such a relationship, these apps lack specific search filters, and so on. That’s why there are specialized dating sites for married men—they do their job much better.
It’s not that bad—it has a large userbase, it’s not too expensive, and everyone knows it. But it’s also not that great compared to the best dating apps for open relationships—the apps like Adult Friend Finder, Ashley Madison, or WannaHookUp have higher reply rates, and they have more users interested in open relationships.
