Verdict

The call

The clearest difference is review sentiment: Lekh at 72% against Lucidchart's 21%. Lekh also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). Lucidchart's advantage is in-app purchases (none vs 2) and rating (4.6 vs 4.2). On price and monetization model there is nothing between them.

Both are free to download. Lekh sells 2 in-app purchases, starting at $3.99 per month. Lucidchart asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Lucidchart holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Lucidchart has 5.3K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 72% of Lekh's written reviews are positive against 21% of Lucidchart's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lekh ships an update fortnightly, Lucidchart every 2 months. Both last shipped on November 1, 2026.
