# CAD FastView vs SiteWorks 2

The clearest difference is review sentiment: SiteWorks 2 at 88% against CAD FastView's 33%. SiteWorks 2 also leads on rating (5.0 vs 4.0). CAD FastView's advantage is ratings volume (50 vs 2) and iOS requirement (15.6 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. CAD FastView sells 3 in-app purchases, starting at $6.99 per 7 days and SiteWorks 2 sells 3 in-app purchases, starting at $17.00 per month. Whichever you choose, the download price is not the number that matters.

SiteWorks 2 holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: CAD FastView has 50 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of CAD FastView's written reviews are positive against 88% of SiteWorks 2's.

CAD FastView ships an update fortnightly, SiteWorks 2 every 3 weeks. The most recent releases landed on October 9, 2026 and October 15, 2026 respectively.
