well for starters there is the most famous tinder, but tinder seems to be quite expensive for their paid subscriptions compared to tantan.
tantan is quite good except that there are many sales people inside who try to sell u gold trading schemes, stock 'tips' so that once u buy, the price will be driven up, but if u r too slow, u get stuck with these shares for a very long time!
i know of 1 guy who seems to be 'scoring' on tantan, getting many 1 night stands! hmm....are girls nowadays so liberal that they also just need to find a male to satisfy their needs n then just call it off? sigh....
