# BOS vs Windmill Air

The clearest difference is rating: Windmill Air at 4.7 against BOS's 2.6. Windmill Air also leads on ratings volume (4.4K vs 80) and update cadence (every 2 months vs every 4 months). BOS's advantage is review sentiment (36% 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 2.6. That said, the two scores are not equally well evidenced: Windmill Air has 4.4K ratings behind it against 80, so its average is the more settled of the two. Written reviews complicate that: 36% of BOS's written reviews are positive against 28% of Windmill Air's, so the app with the better star average is not the one people write more warmly about.

BOS ships an update every 4 months, Windmill Air every 2 months. The most recent releases landed on October 16, 2026 and October 19, 2026 respectively.
