# 青矩online vs 千源题库

青矩online and 千源题库 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. 青矩online sells 2 one-off in-app purchases and 千源题库 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
