# 英単語クイズ vs 進数ノック

The clearest difference is ads: 進数ノック at none against 英単語クイズ's shown. 進数ノック also leads on update cadence (daily vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 英単語クイズ sells 1 one-off in-app purchase and 進数ノック sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

英単語クイズ ships an update fortnightly, 進数ノック daily. The most recent releases landed on October 5, 2026 and October 3, 2026 respectively.
