# 4D VIEWR vs Google Cardboard

The clearest difference is review sentiment: 4D VIEWR at 86% against Google Cardboard's 27%. 4D VIEWR also leads on rating (4.3 vs 2.7). Google Cardboard's advantage is ratings volume (682 vs 6) and update cadence (every 3 months vs every 8 months). 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.

4D VIEWR holds the better App Store score, 4.3 against 2.7. That said, the two scores are not equally well evidenced: Google Cardboard has 682 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 86% of 4D VIEWR's written reviews are positive against 27% of Google Cardboard's.

4D VIEWR ships an update every 8 months, Google Cardboard every 3 months. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
