5 superlikes/day - the thing I bought it for at the time, mostly. Vastly increases a chance to match with exactly the person you like.
Rewind last swipe - helpful. Maybe I have parkinsons or my phone lagged, but I swiped accidentally many times.
See who liked you - just interesting. Reminds you the app is not dead, and you can get immediate matches if wanted.
One boost - a bit more engagement.
