Tinder is brilliant in that it focuses entirely on vanity, ego, and lust, far more so than any of its predecessors. Thus, it has taken a large portion of the dating market away from sites like OKCupid, which had virtually nobody on it in the LA area when I last used it nearly a year ago. Once upon a time, I was an overweight nerd with no money, yet I somehow got dates through OKC. Those days are long gone.
The only alternative I can recommend is real life. Nothing beats it, and it's the only way you can know you aren't wasting your time. Go to meetups and actually talk to people and figure out how to improve when you screw up. Being able to get to know people, even if they don't end up being dates, is pretty awesome. It means actually having to grow as a person, but I would bet on a higher success rate than with any dating app/website.
All dating apps I know of are a joke. Bumble is hilarious because it actually makes an existing problem worse and sells that as a solution; women don't want hundreds of messages from random penises, and they're very unlikely to initiate a conversation.(i don't blame them) Match, Chemistry, PoF, and all those old-school sites are borderline scams that charge a fortune. Match will send you daily emails telling you how many likes(is it "winks"? i can't remember now.) you're getting, but none of that seems to manifest on the site itself. It's the ol' bait and switch.
