# Critter Code vs Train Attack

The clearest difference is ads: Critter Code at none against Train Attack's shown. Critter Code also leads on review sentiment (33% vs 12%) and rating (4.3 vs 4.0). Train Attack's advantage is update cadence (every 11 days vs every 2 months) and ratings volume (967 vs 8). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Critter Code sells 10 one-off in-app purchases and Train Attack sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Critter Code holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Train Attack has 967 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 33% of Critter Code's written reviews are positive against 12% of Train Attack's.

Critter Code ships an update every 2 months, Train Attack every 11 days. Both last shipped on September 25, 2026.
