# Lucidchart vs Diagrams Notepad 3

The clearest difference is rating: Lucidchart at 4.6 against Diagrams Notepad 3's 3.5. Lucidchart also leads on ratings volume (5.3K vs 51). Diagrams Notepad 3's advantage is ads (none vs shown) and review sentiment (39% vs 21%). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Lucidchart sells 2 one-off in-app purchases and Diagrams Notepad 3 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

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.

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.
