I used Luna for quite a while as it was simple, straightforward, worked like a dream, and was completely free. Not one hiccup, one time. Once Apple decided to remove it from the store I began to look for something like it. After some research, and trying other apps that were more “advanced” (and still couldn’t compare to Luna), AdLock seemed to be the answer for complete blockage. During the week trial, there was a point where Full Protection seemed to work, but it was towards the end of said week. I have now paid for the full protection plan and am still seeing ads across all apps. The web-surfing feature works too well, as it doesn’t necessarily block ads so much as kills video streaming completely on some sites.
TLDR: app completely blocks videos with ads in them on browser, and if you pay for the ad-free app “upgrade” you’re still going to see ads in your apps.
