# RaTraPla vs Tuning Simulator

The clearest difference is in-app purchases: RaTraPla at none against Tuning Simulator's 1. Tuning Simulator's advantage is update cadence (every 2 days vs every 3 months) and chart position (#100 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. Tuning Simulator sells 1 one-off in-app purchase. RaTraPla asks for nothing beyond the download.

RaTraPla ships an update every 3 months, Tuning Simulator every 2 days. Both last shipped on November 10, 2026.
