# BIMx vs ArcSite

The clearest difference is rating: ArcSite at 4.7 against BIMx's 4.0. ArcSite also leads on update cadence (weekly vs every 6 weeks) and ratings volume (9.2K vs 168). BIMx's advantage is in-app purchases (none vs 11) and review sentiment (60% vs 45%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. ArcSite sells 11 in-app purchases, starting at $14.99 per month. BIMx asks for nothing beyond the download.

ArcSite holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: ArcSite has 9.2K ratings behind it against 168, so its average is the more settled of the two. Written reviews complicate that: 60% of BIMx's written reviews are positive against 45% of ArcSite's, so the app with the better star average is not the one people write more warmly about.

BIMx ships an update every 6 weeks, ArcSite weekly. The most recent releases landed on October 24, 2026 and November 1, 2026 respectively.
