# 扫描专家 vs 石材链

扫描专家 and 石材链 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. 扫描专家 sells 1 in-app purchase, starting at $4.99 per 7 days and 石材链 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

扫描专家 ships an update every 8 days, 石材链 every 11 days. Both last shipped on October 25, 2026.
