# Count Doku vs Tiny Trains

The clearest difference is rating: Count Doku at 5.0 against Tiny Trains's 4.5. Count Doku also leads on iOS requirement (15.0 vs 18.6). Tiny Trains's advantage is ads (none vs shown) and review sentiment (82% vs 50%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Count Doku sells 8 one-off in-app purchases and Tiny Trains sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Count Doku holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Tiny Trains has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Count Doku's written reviews are positive against 82% of Tiny Trains's, so the app with the better star average is not the one people write more warmly about.

Count Doku ships an update every 3 weeks, Tiny Trains every 3 days. The most recent releases landed on October 21, 2026 and October 28, 2026 respectively.
