hosts are more useful by far doing more for less for more speed, security, reliability, and anonymity
Technically true, but from the screenshot, I notice a lack of wildcards. This is extremely easy to defeat.
And speaking of the hosts file, why not make it a separate download so that one doesn't need to download an executable? The only thing visible from APK is a download link for a closed-source executable as opposed to the hosts file itself. Meanwhile, two other host file databases provide a download that doesn't require a separate installer.
If you going to download a "scary executable", then might as well go whole hog and pick a useful executable file - such as one which can detect new ad networks that popup, and where you can block them on the fly as needed.
You'd be better served being actually useful producing tools of the nature apk
Yes, I have produced a useful tool. It's fully customized for my personal need (which is now complete), and can be trivially adjusted. This would be an intercepting proxy server - even if it slows things down, it has the benefit of caching stuff to either mirror external websites or otherwise allow them to load quicker.
If you want my services (i.e. have that tool converted from specialized to general use), I'm available for 45 USD per hour.
(assuming you can program that is and somehow I doubt you can be that useful).
In that case, I'm available for 60 USD per hour. If you feel that programmers aren't that useful, then you can attempt a better solution yourself, then come to the expert programmers once you mess things up.
