Verdict
The clearest difference is rating: Turnion at 5.0 against Trism's 4.6. Turnion also leads on review sentiment (100% vs 76%) and price ($0.99 vs $2.99). Trism's advantage is ratings volume (232 vs 3) and update cadence (every 3 months vs every 11 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
