# ChessBase Mobile Chess vs ReCall Boost

ChessBase Mobile Chess and ReCall Boost 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. ChessBase Mobile Chess sells 1 in-app purchase, starting at $3.99 per month and ReCall Boost sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
