WinIt's ticket-fighting abilities are owed to its partnership with Empire Commercial Services, a company whose experts claim to have saved business clients more than $250 million in successfully defeated parking tickets. As for the app itself, WinIt says its users have beaten 300 tickets since its launch in March -- a 50% success rate. Of course, that's a small sample size, so those numbers may not hold up.
Another ticket-fighting app based in LA, Fixed, boasts a meager 20% success rate, compared to 28% success rate when going it alone. If WinIt's rates hold, then it'll be a success. But that remains to be seen. Either way, you're paying for convenience -- and have nothing to lose.
If you fancy taking your chances alone, though, you can actually request an online hearing through the department of finance and avoid the hassle of having to fight the ticket in person. Welcome to 2015!
