# Windmill Air vs Wave Spa

The clearest difference is rating: Windmill Air at 4.7 against Wave Spa's 2.0. Windmill Air also leads on ratings volume (4.4K vs 8) and update cadence (every 2 months vs every 3 months). Wave Spa's advantage is review sentiment (46% vs 28%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Windmill Air holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: Windmill Air has 4.4K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 28% of Windmill Air's written reviews are positive against 46% of Wave Spa's, so the app with the better star average is not the one people write more warmly about.

Windmill Air ships an update every 2 months, Wave Spa every 3 months. The most recent releases landed on September 25, 2026 and July 7, 2026 respectively.
