# Mettle vs Tiny Worlds

The clearest difference is rating: Mettle at 4.6 against Tiny Worlds's 4.0. Mettle also leads on in-app purchases (none vs 2) and update cadence (every 2 days vs fortnightly). Tiny Worlds's advantage is review sentiment (100% vs 80%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Tiny Worlds sells 2 in-app purchases, starting at $3.99 per month. Mettle asks for nothing beyond the download.

Mettle holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Mettle has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 80% of Mettle's written reviews are positive against 100% of Tiny Worlds's, so the app with the better star average is not the one people write more warmly about.

Mettle ships an update every 2 days, Tiny Worlds fortnightly. The most recent releases landed on November 10, 2026 and November 1, 2026 respectively.
