# 4D VIEWR vs 4th Wall

The clearest difference is update cadence: 4th Wall at every 11 days against 4D VIEWR's every 8 months. 4th Wall also leads on rating (4.5 vs 4.2) and ratings volume (42 vs 5). 4D VIEWR's advantage is review sentiment (86% vs 67%) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

4th Wall holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: 4th Wall has 42 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 86% of 4D VIEWR's written reviews are positive against 67% of 4th Wall's, so the app with the better star average is not the one people write more warmly about.

4D VIEWR ships an update every 8 months, 4th Wall every 11 days. The most recent releases landed on June 1, 2026 and September 5, 2026 respectively.
