Verdict
The clearest difference is rating: TimeFinder at 4.6 against SEMA3's 3.4. TimeFinder also leads on review sentiment (70% vs 40%) and update cadence (daily vs every 2 months). SEMA3's advantage is in-app purchases (none vs 17). On price, ads and iOS requirement there is nothing between them.
