The perfect app for solar sales-teams and installers who wish to do remote-roof surveys before visiting site to confirm roof dimensions and angles.

Verdict
The clearest difference is rating: Joist at 4.7 against RoofSnoop's 4.3. Joist also leads on ratings volume (15K vs 91) and review sentiment (61% vs 40%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Joist sells 10 in-app purchases, starting at $9.99 per month and RoofSnoop sells 2 in-app purchases, starting at $4.49 per month. Whichever you choose, the download price is not the number that matters.
Joist holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Joist has 15K ratings behind it against 91, so its average is the more settled of the two. Written reviews point the same way: 61% of Joist's written reviews are positive against 40% of RoofSnoop's.
Joist ships an update every 2 weeks, RoofSnoop monthly. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
