# 导线助手 vs ESDPS Survey System

导线助手 and ESDPS Survey System are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. 导线助手 sells 3 one-off in-app purchases and ESDPS Survey System sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
