# 本格プログラミング学習 vs CSS Quiz

本格プログラミング学習 and CSS Quiz are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 本格プログラミング学習 sells 3 in-app purchases, starting at $2.99 per month and CSS Quiz sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

本格プログラミング学習 ships an update every 2 weeks, CSS Quiz fortnightly. The most recent releases landed on September 14, 2026 and September 9, 2026 respectively.
