# 印章 vs 海拔测量器

印章 and 海拔测量器 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. 印章 sells 2 in-app purchases, starting at $3.99 per 7 days and 海拔测量器 sells 2 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
