Verdict

The call

The clearest difference is in-app purchases: AeroEngineS at none against Mechanical Formula's 1. AeroEngineS also leads on update cadence (every 3 days vs every 4 months) and rating (5.0 vs 4.7). Mechanical Formula's advantage is ratings volume (34 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. AeroEngineS asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

AeroEngineS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 1, so its average is the more settled of the two.

UpkeepUpdate frequency

AeroEngineS ships an update every 3 days, Mechanical Formula every 4 months. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
