# Stool Checker vs 今日のうんち

The clearest difference is update cadence: 今日のうんち at every 3 days against Stool Checker's every 6 weeks. Stool Checker's advantage is iOS requirement (12.0 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Stool Checker sells 4 one-off in-app purchases and 今日のうんち sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stool Checker ships an update every 6 weeks, 今日のうんち every 3 days. The most recent releases landed on September 19, 2026 and September 8, 2026 respectively.
