ReceptionRating · Positive reviews · Number of ratings

Kids Note holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Kids Note has 302 ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 74% of Kids Note's written reviews are positive against 85% of 3LINEDIARY's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Kids Note ships an update weekly, 3LINEDIARY fortnightly. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
