Verdict

The call

The clearest difference is ads: LSSI at none against Lucidchart's shown. LSSI also leads on rating (5.0 vs 4.6) and update cadence (fortnightly vs every 2 months). Lucidchart's advantage is ratings volume (5.3K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Lucidchart sells 2 one-off in-app purchases and LSSI sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

LSSI holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Lucidchart has 5.3K ratings behind it against 1, so its average is the more settled of the two.

Lucidchart ships an update every 2 months, LSSI fortnightly. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
