You can change location with Tinder Plus, but your location never actually changes. Girls still see you the distance that your phone geolocates you at. This can be detrimental when you're scouting new places.

Tind3r allows you to swipe extremely fast because it shows your upcoming queue, so you can get a mental image of your queue order: https://i.imgur.com/4ldbG2B.jpg. I can swipe 2-3 girls a second with good accuracy. This is important to me because I think spending a lot of time on my phone/swiping is dangerous, it creates fake dopamine hits without any actual reward.

Thirdly, I run two accounts, one in San Francisco, and one in nearby Contra Costa County (where all the actual hot, feminine girls are, more similar to LA). So I use Tind3r for the latter account.

P.S. I must be living in a different world (e.g. San Francisco) than so many guys, because I almost never get swiped first. 70% of my matches come in on girls I swiped right on first. So using up all my swipes per day matters (I refuse to pay for Tinder Plus because Tinder is so busted here, it's just not that much better than normal Tinder.
