# PoopDiary vs Simple Poop Tracker

The clearest difference is rating: PoopDiary at 5.0 against Simple Poop Tracker's 4.3. Simple Poop Tracker's advantage is update cadence (fortnightly vs every 8 months) and review sentiment (100% vs 83%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. PoopDiary sells 1 one-off in-app purchase and Simple Poop Tracker sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PoopDiary holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 4 and 4 respectively. Written reviews complicate that: 83% of PoopDiary's written reviews are positive against 100% of Simple Poop Tracker's, so the app with the better star average is not the one people write more warmly about.

PoopDiary ships an update every 8 months, Simple Poop Tracker fortnightly. The most recent releases landed on August 27, 2026 and June 4, 2026 respectively.
