As is the case with pretty much all sites run by Cupid Media, it has a beautiful interface with a ton of useful features such as chat, identity verification (important to make sure that people are who they say they are), and an intuitive messaging system.I was a long time member of one of the sister sites of Ukraine Date, Afro Introductions.com, while I was living in both Mauritius and South Africa as an expatriate.
In short, going with a Cupid Media-run site like Ukraine Date will put you in the best position for success.
Your best success with online dating in Ukraine will be in Kiev and Kharkiv.
These two big cities have the largest pools of singles from which to choose. In fact, some of the most beautiful women I have ever seen in my life come from this part of the world.
Dating in Ukraine can be quite fruitful if you have patience and are willing to put in hours of work searching profiles and sending messages.
Also, you will be at a huge advantage if you know how to speak some Russian or Ukrainian since most of the men and women on these sites do not speak a bit of English.
