Tinder pins you to a city you've already left
Tinder, Bumble and Hinge use a fixed GPS radius from your current location. That works fine when you sleep in the same zip code every night. It falls apart when you're in Dallas on Monday, Memphis on Wednesday and Atlanta on Friday.
Every time you cross a state line, Tinder resets your match pool from scratch. The woman you were chatting with on I-20 East of Shreveport doesn't appear in your queue anymore by the time you've delivered in Birmingham. There's no concept of a route - only a single dot on a map.
For OTR drivers running long lanes, this means you're permanently restarting conversations and never building anything. Route-based matching solves the geometry that mainstream apps refuse to fix.
