I think we went tangential from the original topic here. Pics are of great importance on Tinder. It is the very basic and very first criteria I would say that people of the opposite sex would judge you on. That, and your description. I would say you should use pics that show your best self. Pics with a good decent smile, pics that show something you are passionate about, and occasionally pics with dogs and cats works like a charm. Avoid using pics that would look like you're doing a modeling portfolio. Also do not show off those abs. People really don't need to see your topless pics. Those are cringeworthy. Couple of these above mentioned pics combined with a funny witty profile description would work the magic. Be original when you write the description, do not blatantly rip something off the internet.
Coming to the question of whether Tinder works, it's tough to say man. For some it does, for some it doesn't. But don't be disheartened if it doesn't work for you. Like @underfucked_diva suggested, occasionally walk up to a woman and talk to them directly. Trust me there are nice women out there. Be confident, dress nicely, don't be a creep, smile and make her smile and voila!
PS : The above mentioned tips on Tinder works to the best of my knowledge and experience, do not curse me if they don't work
