# 三五小星 vs BrainArk

三五小星 and BrainArk 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. 三五小星 sells 12 in-app purchases, starting at $6.99 per month and BrainArk sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
