Verdict
The clearest difference is price: CodeWiki at Free against UI Tracer's $2.99. CodeWiki also leads on iOS requirement (17.0 vs 26.0). UI Tracer's advantage is update cadence (every 2 days vs every 2 weeks) and chart position (#199 vs unranked). On rating, review sentiment, ads and in-app purchases there is nothing between them.
