Verdict
The clearest difference is review sentiment: TC at 88% against Streemur's 42%. TC also leads on rating (4.8 vs 4.4) and update cadence (every 5 weeks vs every 3 months). Streemur's advantage is price ($2.99 vs $24.99) and iOS requirement (9.0 vs 16.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
