Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. AeroEngineS asks for nothing beyond the download.
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.
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.
