Verdict
Parking Kitty and Trace Viewer both sit at 4.9 stars, but that hides the real split: 100% of Trace Viewer's written reviews are positive against 61% of Parking Kitty's. Trace Viewer also leads on update cadence (fortnightly vs every 35 months). Parking Kitty's advantage is ratings volume (8.8K vs 5) and iOS requirement (13 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
