Verdict
The clearest difference is in-app purchases: Diagnostic App at none against Trofii Racing's 10. Trofii Racing's advantage is update cadence (every 3 days vs every 7 months) and chart position (#208 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
