# ChatEngine vs Clause

ChatEngine and Clause 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. ChatEngine sells 11 in-app purchases, starting at $7.99 per 7 days and Clause sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
