# Roof Guide vs Chippy Tools

The clearest difference is rating: Chippy Tools at 4.5 against Roof Guide's 4.0. Chippy Tools also leads on ratings volume (907 vs 19) and iOS requirement (16.0 vs 26.0). Roof Guide's advantage is review sentiment (64% vs 55%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Roof Guide sells 4 in-app purchases, starting at $1.99 per month and Chippy Tools sells 9 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

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.

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.
