Hahaha Tinder. Oh my, it works yes. You meet people, it has it's moments, but people are weird (at least in my country). It's so awkward man, and when it is not awkward it often ends up being a "one night stand" or something sleazy and damaging like such. I stopped using Tinder quite some time ago. I believe it is bad for the brain as well, swiping through lives like you were in a convenience store.
It's not always the case, but I believe you find deeper connections meeting people in real life. I know it's not always easy and we don't have the time, but for me about 75% of Tinder has been a big waste of time. It's not worth the energy for me, I don't believe that Tinder is a great place to meet a romantic connection, it's cool for friends though - therefore that 25% is kind of almost worth it. I think if there is another app out there with a solid algorithm for matching people then perhaps that would be a better route (I'm not familiar with Badoo). Real life encounters are better IMO.
