ReceptionRating · Positive reviews · Number of ratings

Grid Diary holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Grid Diary has 963 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 48% of Grid Diary's written reviews are positive against 78% of Sync Notion's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Grid Diary ships an update every 2 weeks, Sync Notion every 3 weeks. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
