# 白丁友记 vs 长图拼接

白丁友记 and 长图拼接 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. 白丁友记 sells 3 one-off in-app purchases and 长图拼接 sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
