i don't use it anymore, but here are some tips, i tried couple approaches:
-have more than 4 photos, the first one should be just your face. (Bonus: pic in nice clothes, or in fancy places are very good, because the h0es like that)
-write a short bio (no quotes or dumb shi!t, just something funny) - this is a muss, if you're tall (unlike me) write your height (and add maybe 1 or two inches)
if you don't have the two above you can forget it. after you got matches with the b1tches, send them max 6-8 messages, then cut the bull sh1t and ask for her phone number. (or even better, just give it to her to check her IL) don't write anything too sexual or too cheesy, and defintly don't text too much (because there are lot of orbiters there) - it means that when you get her # you should already have her agreeing to meet, otherwise you're probably gonna waste your time.
when you got her # you can start being more sexual and flirty. there are many approaches, some guys will text more, some less. my advice is as said, if you got her number, you should suggest the date pretty quickly, and don't call her untill you guys met for the first time. the problem with those b1tches is that they got too many options, so you should stand out with your texts, be mysterious. i repeat: DONT text too much, they will flake you, and DONT waste too much time on them.
another advice: a lot of b1tches will look very nice on tinder, but in real life they are maybe 4-5ish. meeting for a coffee just to see if she is f**kable is also a good apporach. i've digged some b1tches that i otherwise would never have, just because the situation was already set.
tinder is sh!t, if you're average to good looking, dont expect too much, its all or nothing in tinder, most of b1tches are looking for white, tall, masculine male.
