Airfoil Design is the ultimate tool for designing and analyzing aircraft wing sections. With advanced numeric methods, custom mesh generation, and real-time aerodynamic analysis, you can create and refine complex airfoil geometries with precision. Our CFD simulation engine accurately solves Euler's equations, providing insights into compressible, non-viscous flows, including shockwave formations. Key Features: - Design Flexibility: Generate and customize airfoil geometries with 4 types: NACA 4-digit, NACA 5-digit, Modified NACA 4-digit, and Modified NACA 5-digit airfoils. - Real-Time Analysis: Adjust airfoil shapes using intuitive sliders and instantly see the impact on aerodynamic coefficients. - Airfoil Import: Easily import existing airfoils from the airfoiltools.com database. - Custom Mesh Generation: Create o-type grid meshes with our built-in generator and export them for use in other applications. - Advanced CFD Simulation: Simulate airflow around your designs with our powerful CFD engine, now featuring touch pan/zoom, streamlines, CP vectors, and second-order solver. Visualize results with the new Coolwarm color map and export them as PDFs. Whether you’re a professional aerospace engineer or a student of aerodynamics, Airfoil Design offers the tools you need to innovate and explore. Download now to start your aerodynamic journey on your iPad or iPhone. Note: The app is continuously being improved, with new features and bug fixes on the way.

Verdict
The clearest difference is rating: ONELAB at 5.0 against Airfoil Design's 3.9. ONELAB also leads on review sentiment (100% vs 63%) and iOS requirement (9.0 vs 16.0). Airfoil Design's advantage is update cadence (every 10 days vs every 2 months) and ratings volume (17 vs 1). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
ONELAB holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Airfoil Design has 17 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of ONELAB's written reviews are positive against 63% of Airfoil Design's.
ONELAB ships an update every 2 months, Airfoil Design every 10 days. The most recent releases landed on June 8, 2026 and September 11, 2026 respectively.
