# Ignis vs Shells

The clearest difference is review sentiment: Shells at 100% against Ignis's 60%. Shells also leads on update cadence (weekly vs every 6 weeks) and rating (5.0 vs 4.7). Ignis's advantage is ratings volume (7.9K vs 22). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Ignis sells 9 one-off in-app purchases and Shells sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
