Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Piary sells 1 one-off in-app purchase and Diary! SmartDiary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Piary holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Diary! SmartDiary has 44 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of Piary's written reviews are positive against 93% of Diary! SmartDiary'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, Diary! SmartDiary every 3 months. The most recent releases landed on June 1, 2026 and September 17, 2026 respectively.
