Verdict
The clearest difference is rating: WebFX at 4.8 against Duality Pro's 4.1. WebFX also leads on review sentiment (87% vs 56%) and monetization model (free with in-app purchases vs paid). Duality Pro's advantage is update cadence (monthly vs every 2 months) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. WebFX sells 4 in-app purchases, starting at $1.99 per month and Duality Pro sells 5 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
WebFX holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: WebFX has 112 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 87% of WebFX's written reviews are positive against 56% of Duality Pro's.
WebFX ships an update every 2 months, Duality Pro monthly. Both last shipped on October 7, 2026.
