It's functions similar to other mobile ad-blockers in that it can route all your phones traffic over a VPN tunnel it establishes.

But the ad-blocking vpn server is 127.0.0.1, so perhaps, like it says all the blocking happens right on your phone.

This is what I've been waiting for if this works.

Still getting ads on instagram though.

For an open source app distributed on the App Store, is there actually any way of verifying that what you get on your phone is the same as the source code you can read?

If Apple keeps pushing their Bitcode LLVM IR trans-compiling, along with magic App Store re-linking, they will kill the possibility of reproducible builds forever. In Apple's world, you are supposed to trust their app vetting process, not the source code on some website.

On Android, DNS66 does exactly this, available on F-Droid. https://f-droid.org/en/packages/org.jak_linux.dns66/

Looks like the core of this is done via https://developer.apple.com/documentation/networkextension

some cool stuff here:

Is there anywhere with an in-depth overview of what this does? Does it just fail DNS request and block known IPs? How are the lists maintained and updated? With TLS and it surely not mitm-ing connections, that's all it can do correct?

The source indicates that they check-in DNS blocklists as JSON files [0] and txt files (one of which has Facebook IPv4s) [1]. So, the updates to those would require app updates, I guess, unless there's OTA for the blocklists somewhere in the code that I missed. My experience with running client-side DNS based blockers are they consume additional battery and need a lot of RAM if you block with aggressive lists that ha…

are you saying the same group of subcontractors built them all? or that it's the same app repackaged multiple times? or something else?

i use adguard on iOS and while i don't like the first-party exposure (to adguard itself), it's better than being completely naked in public to all sorts of shady actors (including telecom/wireless providers). or is it?

It's "open source", but there's only been 5 commits since August last year? Where do the updates to blocking rules etc come from?

Also, the homepage states "Over 1 Billion Trackers Blocked", but that really feels misleading.

I'd say Guardian Firewall is a much better choice: https://twitter.com/guardianiosapp

No. Sorry, I meant that the creators of lockdownhq also built confirmedvpn.

> or something else?

Yes. Alternatives.
