ReceptionRating · Positive reviews · Number of ratings

Lucidchart holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: Lucidchart has 5.3K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 21% of Lucidchart's written reviews are positive against 39% of Diagrams Notepad 3's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lucidchart ships an update every 2 months, Diagrams Notepad 3 monthly. The most recent releases landed on August 31, 2026 and June 9, 2026 respectively.
