# Kutta Joukowski vs Pixel Wind Tunnel

The clearest difference is ads: Kutta Joukowski at none against Pixel Wind Tunnel's shown. Kutta Joukowski also leads on monetization model (free vs ad-supported) and iOS requirement (7.1 vs 15.0). Pixel Wind Tunnel's advantage is update cadence (every 7 months vs every 52 months). On price, review sentiment, 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.

Kutta Joukowski ships an update every 52 months, Pixel Wind Tunnel every 7 months. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
