# Hmmsim vs Train Simulator Rails Strategy

The clearest difference is review sentiment: Hmmsim at 70% against Train Simulator Rails Strategy's 12%. Hmmsim also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Train Simulator Rails Strategy's advantage is rating (4.3 vs 3.8) and ratings volume (3.4K vs 168). On price, update cadence, 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 Simulator Rails Strategy holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: Train Simulator Rails Strategy has 3.4K ratings behind it against 168, so its average is the more settled of the two. Written reviews complicate that: 70% of Hmmsim's written reviews are positive against 12% of Train Simulator Rails Strategy's, so the app with the better star average is not the one people write more warmly about.

Hmmsim ships an update every 5 months, Train Simulator Rails Strategy every 3 months. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
