ReceptionRating · Positive reviews · Number of ratings

Chippy Tools holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Chippy Tools has 907 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 64% of Roof Guide's written reviews are positive against 55% of Chippy Tools's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Roof Guide ships an update every 2 weeks, Chippy Tools every 8 days. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
