It totally is. Limited likes, instant matches with Super Like and I assume the same with boosts, and rewinds if you screw up.
I might drop the 20 bucks on the monthly thing to see if it makes much difference if the app seems any good.. So far I'm noticing there are a huge number of women I'm uninterested in on here, and odds are just shitty if you don't have a way to get your profile to someone you'd match with so I'm skeptical so far.
I found other ways to get plus/gold feature for free.
