# SClock vs 郵便番号さがし

SClock and 郵便番号さがし 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. SClock sells 1 in-app purchase, starting at $0.99 per month and 郵便番号さがし sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
