Try Adguard's DNS content blocker. I bought the pro version to control access with a custom VPN, and that enables it to filter your cellular traffic, not just wifi. The app runs a local VPN on your iPhone, and you can block analytics domains. Here are some things I've blacklisted and prevented common apps from connecting to: settings.crashlytics.com data.flurry.com graph.facebook.com google-analytics.com adobemobiledev.sc.omtrdc.net api.leanplum.com So you can deny connections to a lot of shady websites, and in total I'm blocking around 100 different domains. No more web fonts from Google, no Facebook or social media connections through apps or websites, and it's great.
