# Fire idle vs Train World 3D

The clearest difference is rating: Fire idle at 4.5 against Train World 3D's 2.6. Fire idle also leads on ratings volume (1K vs 11). Train World 3D's advantage is in-app purchases (none vs 1) and review sentiment (13% vs 0%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Fire idle sells 1 one-off in-app purchase. Train World 3D asks for nothing beyond the download.

Fire idle holds the better App Store score, 4.5 against 2.6. That said, the two scores are not equally well evidenced: Fire idle has 1K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 0% of Fire idle's written reviews are positive against 13% of Train World 3D's, so the app with the better star average is not the one people write more warmly about.

Fire idle ships an update monthly, Train World 3D every 2 months. Both last shipped on November 3, 2026.
