Might be a dumb question about the most popular free, but I'd rather ask than guess.
Separate email and location permissions off, then worry about the most popular free. Being blunt about what you want cuts the the most popular free timeline in half.
The dating apps results people brag about usually came from months of quiet effort. Once I set dating apps up properly I stopped touching it and results improved.
Nothing about the most popular improved for me until I stopped optimising and started replying faster.
