4th Wall is a free, augmented reality (AR) public art platform exploring inclusive creative expression. “Coordinates” hosts an ongoing series of curated, collaborative, site specific, public AR art exhibitions. Users are invited to be physically present at specific locations to experience AR artworks in situ. When users select the Coordinates feature, based on their location, they will be directed toward artworks – translated into AR-- created by artists that activate the historically, politically or culturally significant sites they have chosen. “Coordinates” aims to inspire thoughtful dialogue and expand our understanding of public art. By pressing the AR Artworks button, users can view, explore and place Nancy Baker Cahill’s dimensional drawings in the environment of their choice. Drawings can be rotated, scaled, placed and recorded by user. What’s New - A more streamlined experience for the user, with the removal of the hologram, studio experience and Desert X exhibition buttons and an expansion of the curated and site-specific “Coordinates” AR public art exhibitions platform. - Artworks may include sound so make sure to check for the new orange sound button at the top of the menu when observing an artwork on site. - The “Refresh” button updates the nearest artwork depending on the user’s location. - The “About” button directs users to the home page for 4thwallapp.org.

Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
