# Flash vs AtlaBuild

The clearest difference is rating: AtlaBuild at 5.0 against Flash's 4.0. AtlaBuild also leads on review sentiment (100% vs 67%) and update cadence (weekly vs monthly). Flash's advantage is ratings volume (49 vs 3) and iOS requirement (11.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
