# 刻意自学 vs 背书帮

刻意自学 and 背书帮 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. 刻意自学 sells 9 in-app purchases, starting at $17.99 per month and 背书帮 sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

刻意自学 ships an update every 6 days, 背书帮 every 10 days. The most recent releases landed on October 23, 2026 and October 8, 2026 respectively.
