# Area Quiz vs フラッシュ暗算DX

The clearest difference is rating: Area Quiz at 4.9 against フラッシュ暗算DX's 3.0. Area Quiz also leads on review sentiment (63% vs 30%) and ratings volume (11 vs 2). フラッシュ暗算DX's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Area Quiz sells 2 one-off in-app purchases and フラッシュ暗算DX sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Area Quiz holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Area Quiz has 11 ratings behind it against 2, so its average is the more settled of the two.
