3Fun Alternative and Apps Like 3Fun for Couples
A 3Fun alternative makes sense when you want the same thing 3Fun promises, a third or a couple to play with, but with stricter checks on who is on the other side. Sinners verifies the age and identity of every member, lets a couple share one profile with both partners verified, shows boundaries before the first message and keeps photos blurred until you unlock them. If you are planning a threesome and want fewer fakes, this is the app built for it.
What is the best alternative to 3Fun?
For couples who want a real third rather than more browsing, the best alternative to 3Fun is an app where every member passes an ID and selfie check and both partners of a couple are verified. Sinners works that way. Feeld is the other app most people try, and it suits singles who are exploring more than couples who already know what they want.

3Fun wins on price for a first look: you can match and message matches without paying, and that matters if you only want to see who is around. It also has a long history as a dedicated threesome app. Where couples tell us it falls short is certainty about who they are talking to. Check 3Fun's app store listing for its current VIP price, since it changes by country and over time.
Why couples look for apps like 3Fun with stricter checks
A threesome needs three people who are real, who agree on the plan and who will keep it private. The usual frustrations on broad threesome apps hit all three. Profiles that turn out to be one man posing as a couple. Single women who stop replying because their inbox is full. Photos screenshotted and passed around. And the long chat it takes to discover that one of you wants full swap and the other wants a drink and a kiss.
Security has also been a theme. In 2019 researchers at Pen Test Partners reported that 3Fun exposed users' locations and private photos. The company said it fixed the issues and later announced penetration testing with an outside firm. That history is the reason many couples now ask a direct question before they pay: who checks the people I am about to meet, and who can see my photos?
What Sinners does differently for threesomes
-
Both partners verified
Each partner of a couple completes the document and selfie check. The profile shows as a verified couple only when both of you pass, so a single woman knows the other half of the couple is real too.
-
Boundaries before the first hello
Who touches whom, same room or not, kissing, protection, sleepovers. You tick what is on the table, and the boundary match shows the overlap before anyone writes. The first message can be about meeting, not about rules.
-
A single woman controls her inbox
Unicorns choose who can reach them: verified couples only, an age range, a distance. Messages outside those settings never arrive, which is why single women stay and reply.
-
Single men who get answers
Couples who want a man filter for verified single men with clear boundaries. The verified badge plus a specific profile gets far more replies than a shirtless photo.
-
Photos you can take back
Blurred until unlock, private albums shared one person at a time and access you can revoke later. No real names on any profile.
How to switch from 3Fun to Sinners
Agree on the plan together
Before anyone downloads anything, write down what you both want. Woman, man or either. Soft or full. Same room or separate. Our guide on how to find a third walks through the conversation most couples skip.
Build one couple profile
Pick a nickname, describe yourselves as a couple, add photos and choose a privacy level. Blurred until unlock is the usual choice for couples who are not out.
Verify both of you
A document and a live selfie each. It takes a few minutes and the badge is what makes a single take you seriously.
Search, then message together
Filter by profile type, distance and boundaries, then write from the shared inbox so both partners see every reply.

3Fun alternative questions
Is there an app better than 3Fun?
It depends on what you need. If you want to browse for free, 3Fun is hard to beat. If you want every member checked with an ID and a live selfie, both partners of a couple verified and boundaries visible before chat, Sinners is the better fit for couples who are ready to meet.
What apps are like 3Fun?
The apps most like 3Fun are Feeld, which suits singles exploring open and kink dating, and Sinners, which is built for couples, unicorns and lifestyle singles with verification and boundary matching. Older swinger sites such as SDC also have threesome seekers but focus on couples meeting couples.
Is 3Fun safe to use?
3Fun had a reported security flaw in 2019 that exposed locations and photos, and the company says it fixed it and added outside penetration testing. Whatever app you use, keep your face blurred until you trust someone, meet first in a public place and never share your real name early.
Can a single woman use Sinners without being flooded with messages?
Yes. A single woman decides who can message her, for example verified couples only within a set distance and age range. Messages outside those settings are not delivered, so she sees only the profiles she chose to hear from.
Does one membership cover both partners?
Yes. The Couples plan covers both partners on one shared profile for 59 USD per month, or 29 USD per month billed yearly. Both of you use the same inbox, albums and boundary list.
