# 大夏书系 vs 北教辅学

大夏书系 and 北教辅学 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. 大夏书系 sells 7 one-off in-app purchases and 北教辅学 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

大夏书系 ships an update monthly, 北教辅学 fortnightly. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
