# Wingload calculator vs VOG

The clearest difference is rating: Wingload calculator at 5.0 against VOG's 4.2. Wingload calculator also leads on iOS requirement (10.0 vs 12.0). VOG's advantage is review sentiment (33% vs 0%) and update cadence (weekly vs every 3 weeks). 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.

Wingload calculator holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: VOG has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Wingload calculator's written reviews are positive against 33% of VOG's, so the app with the better star average is not the one people write more warmly about.

Wingload calculator ships an update every 3 weeks, VOG weekly. Both last shipped on November 3, 2026.
