# iAntiTheft vs UPX Private Browser

The clearest difference is ads: iAntiTheft at none against UPX Private Browser's shown. iAntiTheft also leads on review sentiment (64% vs 41%) and iOS requirement (13.0 vs 17.0). UPX Private Browser's advantage is ratings volume (8.8K vs 1.2K). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. iAntiTheft sells 1 one-off in-app purchase and UPX Private Browser sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for iAntiTheft against 4.6 for UPX Private Browser. That said, the two scores are not equally well evidenced: UPX Private Browser has 8.8K ratings behind it against 1.2K, so its average is the more settled of the two. Written reviews are what separate them: 64% of iAntiTheft's written reviews are positive against 41% of UPX Private Browser's.
