# Linkus2 vs 9Star

Linkus2 and 9Star 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. Linkus2 sells 12 in-app purchases, starting at $2.99 per month and 9Star sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
