# 钉题库 vs 优题宝

钉题库 and 优题宝 are too close to call on the numbers: across 7 compared parameters — price, review sentiment, update cadence and ads 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. 钉题库 sells 23 one-off in-app purchases and 优题宝 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 23, 2026 and August 29, 2026 respectively.
