What does it mean ?
I think that stands for Instagram, SnapChat, and Twitter, respectively. Elon Musk officially renamed Twitter to X for whatever silly reason.
None of them really make any sense to me, but I guess are more popular with much younger individuals, like early 20s.
Anyway, to answer the OP's question, even though I'm not that big yet...
If I was to consider such a thing, there's no point in considering anything besides the mainstream platforms. The entire concept is extremely sensitive to "network effect" as I've mentioned in relation to dating web sites in general. In short, the service is far more useful to existing users, the more users in general there are.
After all, what good is some random niche dating web site if there's only 5-6 people in your area, and none of them are even close to your type? Or haven't logged in to the web site in months, or even years?
No, regardless of taste, preference, or type, the mainstream platforms are the only ones to consider using, just for sheer maximum numbers.
In America, that would probably be Match Group (Match, POF, e-Harmony if Christian, Tinder, and maybe some others) and Badoo. OKCupid and Zoosk have lost ground but might still have some users.
In other countries, I don't know. You can probably guess by looking at the Google Play Store or the Apple Store to look a total download count.
Ignore the ads, and anything a so-called "influencer" might say, because they're being paid to say it's good even if it's bad.
Above all, don't lower your standards, but keep your expectations out of web sites like that very low. I have found a lot of people are overly cautious and even afraid - some of it justified to be fair, but not entirely. Most folks out there are decent. In a world where news travels at light speed, the few who are bad, suddenly everyone hears about them. Just make the first meeting in a public place that's quiet enough that you can talk, and you'll be fine.
