# Ferromagnetic vs Crate.

The clearest difference is rating: Ferromagnetic at 4.0 against Crate.'s 3.4. Ferromagnetic also leads on ads (none vs shown) and ratings volume (24 vs 8). Crate.'s advantage is in-app purchases (none vs 6) and review sentiment (92% vs 80%). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Ferromagnetic sells 6 in-app purchases, starting at $2.49 per month. Crate. asks for nothing beyond the download.

Ferromagnetic holds the better App Store score, 4.0 against 3.4. Both are backed by a comparable volume of ratings — 24 and 8 respectively. Written reviews complicate that: 80% of Ferromagnetic's written reviews are positive against 92% of Crate.'s, so the app with the better star average is not the one people write more warmly about.
