# Piary vs おとなの日記帳

The clearest difference is rating: Piary at 5.0 against おとなの日記帳's 4.6. おとなの日記帳's advantage is review sentiment (85% vs 75%) and ratings volume (21 vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Piary sells 1 one-off in-app purchase and おとなの日記帳 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Piary holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 6 and 21 respectively. Written reviews complicate that: 75% of Piary's written reviews are positive against 85% of おとなの日記帳's, so the app with the better star average is not the one people write more warmly about.

Piary ships an update every 3 weeks, おとなの日記帳 monthly. The most recent releases landed on June 1, 2026 and September 19, 2026 respectively.
