# Zen Idle vs Grimoire Incremental

The clearest difference is review sentiment: Grimoire Incremental at 87% against Zen Idle's 54%. Grimoire Incremental also leads on rating (4.8 vs 4.6). Zen Idle's advantage is update cadence (every 10 days vs every 3 months) and ratings volume (2.9K vs 556). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zen Idle sells 12 one-off in-app purchases and Grimoire Incremental sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
