# T vs iQ Viewer

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iQ Viewer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: T has 208K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 25% of T's written reviews are positive against 100% of iQ Viewer's.

T ships an update every 4 months, iQ Viewer every 3 weeks. The most recent releases landed on November 1, 2026 and October 13, 2026 respectively.
