Verdict
The clearest difference is rating: WingX® at 3.6 against Sky's 3.0. WingX® also leads on ratings volume (181 vs 1). Sky's advantage is review sentiment (83% vs 47%) and update cadence (monthly vs every 2 months). On price, ads, in-app purchases and monetization model 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
Both are free to download. Sky sells 12 one-off in-app purchases and WingX® sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
WingX® holds the better App Store score, 3.6 against 3.0. That said, the two scores are not equally well evidenced: WingX® has 181 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Sky's written reviews are positive against 47% of WingX®'s, so the app with the better star average is not the one people write more warmly about.
Sky ships an update monthly, WingX® every 2 months. The most recent releases landed on October 1, 2026 and October 8, 2026 respectively.
