Forget mainstream dating apps for your fetish and kinky desires. SiN is packed with like-minded singles with needs that match. Download the app right now, if you dare!

SiN is an exciting place to connect with like-minded singles interested in fetishes, fantasy, role-play, bondage and numerous other kinks and kinky passions. Maybe you have tried a mainstream dating app before but just end up wasting time as your desires are never met? Get straight through to the right kind of singles with SiN! Start chatting online and then take it into the real world!


SiN is a community of kinksters with a range of experience levels. Some fetish sites, in our opinion, are just too extreme, SiN is an approachable app for all. SiN has everything you need to search, chat and date all wrapped up in a pixel perfect display.

The SiN app is not swipe-based nor does it have any silly gamification that gets in the way of meeting people, life is too short for all that rubbish. If you see someone you like, send them a HOT alert or send them a private and direct message.


SiN enables kinky singles to:

· Search other members
· Read profiles
· Upload multiple pictures
· Set a local city
· Set a non-local city for people traveling
· Reply to messages and swap pictures
· Select multiple interests
· See who viewed your profile
· + a lot more

The team behind SiN have won multiple dating industry awards and have been creating meaningful relationships for over 12 years.


SiN users can be male, female, couples and transgender from the ages of 18 to 99 and be any sexuality, you can select sex and sexuality in whatever combination defines you. SiN users are interested in bondage, BDSM, swinging, casual partners, hookups, friendship, and serious relationships.


When SiN was created we thought about how to reduce the amount of personal data that is requested. Users can select an alternative first name, set age and not the date of birth, sexuality can be private and passwords are encrypted in such a way they are near impossible to decode. When you decide to leave SiN all your data is erased forever, it’s as if you never joined. We also don’t force you to have a picture nor do we connect up your Facebook account! All message data is automatically erased after a set period. The only personal information you need to enter is an email address and we even suggest you make a new one just for dating purposes. This way you can be anonymous.

SiN is free to download and free to send an introduction and hot messages, search and browse profiles. A VIP subscription may be purchased to allow unlimited messages both locally and internationally. We offer weekly, monthly, 3-month and 6-month subscriptions. The prices are in local currency and clearly displayed on the VIP upgrade page. Prices are subject to change without notice.

No communication

I have paid $70.00 for Six months. I haven’t received one message . This company has other apps. I think that I would be better off switching to another company owned app and transferring my VIP status without penalty or paying.
It’s now December and I feel ripped off. Cybersex app got no responses and sin was nothing but a paid app
For people that want you to paid them. I’m a married man without a sex life . I just want online sex with no dating.

Developer Response ,

Please get in touch and we can give you access to any of the other sites / apps we operate. We want you to be a happy 5 star customer. Use the settings menu > support option.

I’m giving this app no star

Sh*me to the makers of this app you can’t just start blocking people out because they’re scammers everywhere I live in Washington state my account just got blocked with a message saying *BLOCKED SCAM SOMEWHERE ELSE * That’s nonsense very inappropriate

Mostly fake mostly scams

Nobody messages and nobody replies. The few that reach out are fake scam profiles asking you join a sex website. This site is a joke.
