# 豆豆指南针 vs AR Compass 3D

The clearest difference is rating: AR Compass 3D at 4.6 against 豆豆指南针's 4.0. AR Compass 3D also leads on ratings volume (36 vs 3). 豆豆指南针's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 75%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AR Compass 3D sells 1 one-off in-app purchase. 豆豆指南针 asks for nothing beyond the download.

AR Compass 3D holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: AR Compass 3D has 36 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of 豆豆指南针's written reviews are positive against 75% of AR Compass 3D's, so the app with the better star average is not the one people write more warmly about.

豆豆指南针 ships an update every 3 months, AR Compass 3D every 2 months. The most recent releases landed on August 17, 2026 and September 25, 2026 respectively.
