Verdict

The call

The clearest difference is in-app purchases: Tenio at none against Circuit Simulator's 8. Tenio also leads on rating (5.0 vs 4.7). Circuit Simulator's advantage is ratings volume (93 vs 2) and update cadence (every 2 months vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
