Verdict
The clearest difference is review sentiment: EasySoap at 100% against Windmill Air's 28%. EasySoap also leads on update cadence (fortnightly vs every 2 months). Windmill Air's advantage is price (Free vs $1.99) and rating (4.7 vs 3.5). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Windmill Air is free to download; EasySoap costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Windmill Air holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Windmill Air has 4.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 28% of Windmill Air's written reviews are positive against 100% of EasySoap'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, EasySoap fortnightly. The most recent releases landed on October 17, 2026 and October 5, 2026 respectively.
