ReceptionRating · Positive reviews · Number of ratings

RoofSnoop holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: RoofSnoop has 91 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 40% of RoofSnoop's written reviews are positive against 50% of STACK Construction Management's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RoofSnoop ships an update monthly, STACK Construction Management fortnightly. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
