Verdict
The clearest difference is review sentiment: iQ Viewer at 100% against T's 25%. iQ Viewer also leads on update cadence (every 3 weeks vs every 4 months) and rating (5.0 vs 4.7). T's advantage is ratings volume (208K vs 1) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.
