# AppLock vs Black Box

The clearest difference is rating: Black Box at 4.7 against AppLock's 3.8. Black Box also leads on ads (none vs shown) and monetization model (free vs ad-supported). AppLock's advantage is iOS requirement (14.0 vs 16.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

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

Black Box holds the better App Store score, 4.7 against 3.8. Both are backed by a comparable volume of ratings — 35 and 41 respectively. Written reviews complicate that: 69% of AppLock's written reviews are positive against 67% of Black Box's, so the app with the better star average is not the one people write more warmly about.
