Verdict
The clearest difference is update cadence: VIN Decode RPO at every 3 days against TopScan Pad's every 4 months. VIN Decode RPO also leads on rating (4.8 vs 4.4) and ratings volume (36 vs 5). TopScan Pad's advantage is monetization model (free vs ad-supported) and iOS requirement (11.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.
