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 ads: Airfoil Design at none against SAFE Toolkit's shown. Airfoil Design also leads on update cadence (every 10 days vs every 7 months) and review sentiment (63% vs 38%). SAFE Toolkit's advantage is rating (4.2 vs 3.9) and iOS requirement (11.0 vs 16.0). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SAFE Toolkit holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 18 and 17 respectively. Written reviews complicate that: 38% of SAFE Toolkit's written reviews are positive against 63% of Airfoil Design's, so the app with the better star average is not the one people write more warmly about.
SAFE Toolkit ships an update every 7 months, Airfoil Design every 10 days. The most recent releases landed on September 14, 2026 and September 11, 2026 respectively.
