# Engine Simulator vs Nitro Apex

The clearest difference is ads: Engine Simulator at none against Nitro Apex's shown. Engine Simulator also leads on chart position (#47 vs unranked). Nitro Apex's advantage is update cadence (every 3 days vs every 2 months) and iOS requirement (15.0 vs 18.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Engine Simulator sells 1 one-off in-app purchase and Nitro Apex sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Engine Simulator ships an update every 2 months, Nitro Apex every 3 days. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
