# 超级错题本 vs QuickErrNote

超级错题本 and QuickErrNote 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. 超级错题本 sells 1 one-off in-app purchase and QuickErrNote sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 3, 2026 and September 29, 2026 respectively.
