The call

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).

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
