# Chain Bump! vs Train Maker

The clearest difference is rating: Train Maker at 4.7 against Chain Bump!'s 3.9. Train Maker also leads on ratings volume (865 vs 8). Chain Bump!'s advantage is update cadence (every 3 weeks vs every 3 months) and monetization model (ad-supported vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Train Maker holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Train Maker has 865 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 84% of Chain Bump!'s written reviews are positive against 76% of Train Maker's, so the app with the better star average is not the one people write more warmly about.

Chain Bump! ships an update every 3 weeks, Train Maker every 3 months. The most recent releases landed on October 12, 2026 and October 11, 2026 respectively.
