# CaseFox vs Zero

The clearest difference is rating: Zero at 5.0 against CaseFox's 3.3. CaseFox's advantage is review sentiment (36% vs 25%) and iOS requirement (13.0 vs 17.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Zero holds the better App Store score, 5.0 against 3.3. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 36% of CaseFox's written reviews are positive against 25% of Zero's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on July 4, 2026 and June 23, 2026 respectively.
