I'm looking for a free, reputable ad blocker on the Play Store. Something that does local host/filter list filtering using the VPN feature, like Blokada 4 or 5 (before they started cloud hosting the filtering features as a money/data grab).

Personally, I'm no stranger to F-Droid or Obtanium and even have dipped my toes into ADB.

I need this for family members when they start asking, so I can point them at something decent that won't try to fleece them and get on with my life unburdened by family tech support hell. Something they can install through the Play Store they already have and easily switch on and off if something they "need" isn't working.

So that eliminates just setting their DNS to an ad blocking one in their Wi-Fi settings. Wouldn't follow them off that specific connection, and wouldn't be an easy toggle if something broke.
