# Linearity Curve Graphic Design vs Sigil Code

The clearest difference is review sentiment: Sigil Code at 100% against Linearity Curve Graphic Design's 61%. Sigil Code also leads on rating (4.8 vs 4.5). Linearity Curve Graphic Design's advantage is ratings volume (14K vs 4) and update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Linearity Curve Graphic Design sells 15 in-app purchases, starting at $7.99 per 7 days and Sigil Code sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Linearity Curve Graphic Design has 14K ratings behind it against 4, so its average is the more settled of the two.
