Verdict
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.
