# Trans4motor vs Steam Engines

The clearest difference is rating: Steam Engines at 5.0 against Trans4motor's 3.7. Steam Engines also leads on in-app purchases (none vs 1) and chart position (#193 vs unranked). Trans4motor's advantage is ratings volume (70 vs 1). On ads, device support and iOS requirement there is nothing between them.

Trans4motor costs $2.99 and Steam Engines $0.99 up front. Trans4motor sells 1 one-off in-app purchase. Steam Engines asks for nothing beyond the download.

Steam Engines holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Trans4motor has 70 ratings behind it against 1, so its average is the more settled of the two.
