# Lucidchart vs LSSI

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.

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.

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.
