JDate has been connecting single Jews online since 1997.
It's by far the largest Jewish dating service with hundreds of thousands of members worldwide.
If you're curious and decide to try Jewcier, here's the link.
Jsingles isn't nearly as big as JDate or Match.com, so you're not going to find as many potential matches.
However, it's a very distant second behind JDate.com, which means there are far fewer singles.
I can overlook this because of all the other great features of the site.
After you’ve completed a search, you can sort the list of members by newest, most active, closest to you and most popular.
The website is popular in America, Israel, Canada, Australia, and the UK.
JDate's subscription fee is a little more than the others on this page, but your odds of finding matches are much higher because there are thousands of Jewish singles in the database.
There are plenty of services that you can use, but only a few of them are really any good.
