Verdict
The clearest difference is rating: Builder Signal at 3.7 against BIM 360's 1.8. Builder Signal also leads on update cadence (every 3 weeks vs every 2 months). BIM 360's advantage is ratings volume (148 vs 6) and device support (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Builder Signal holds the better App Store score, 3.7 against 1.8. That said, the two scores are not equally well evidenced: BIM 360 has 148 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 5% of BIM 360's written reviews are positive against 0% of Builder Signal's, so the app with the better star average is not the one people write more warmly about.
BIM 360 ships an update every 2 months, Builder Signal every 3 weeks. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
