Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Windmill Air ships an update every 2 months, Wave Spa every 3 months. The most recent releases landed on September 22, 2026 and July 7, 2026 respectively.
