I'm looking for a content blocker, or failing that an adblocker for iPhone 5.
Now I wouldn't ask this question here without a little research. All the adblockers (free of charge and paid) which I found required iOS 9.x (which I have) and an iPhone 5s (which I don't have). The important point is, that the iPhone 5s was - to my knowledge - the first iPhone with a 64-bit CPU. So aside from the fact that the app store will simply refuse to install anything not compatible with my device, there seems to be an actual underlying reason.
Can anyone here point out such software compatible with iPhone 5 and perhaps even down to iPhone 4?
