# Poo Diary vs PoopDiary

The clearest difference is review sentiment: PoopDiary at 83% against Poo Diary's 9%. PoopDiary also leads on rating (5.0 vs 3.0). Poo Diary's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 8 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Poo Diary sells 1 in-app purchase, starting at $2.99 per year and PoopDiary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
