Original Summary

Hi everyone, I made an open-source Android app called AppDNS. It automatically changes Android's built-in Private DNS (DNS-over-TLS) depending on which app you open. For example: AdGuard DNS for your browser, Quad9 for banking, and Private DNS off for an app that breaks with filtering. How it works - It writes directly to Android's native Private DNS settings, so it does NOT use a VPN slot. WireGuard/Tailscale keep working. - A lightweight accessibility service detects which app is in the foreground and applies that app's DNS. When you leave, it turns Private DNS off or restores your default (your choice). - Quick Settings tiles to toggle Private DNS or cycle through saved providers. - Preloaded providers: AdGuard, Cloudflare (incl. family/security), Quad9, NextDNS, Mullvad, Control D, Google. You can also add custom hostnames. - Built-in latency test for each resolver. - No analytics, no tracking. Everything stays on the device. Setup (one-time) It needs the WRITE_SECURE_SETTINGS permission. Grant it with one ADB command, via Shizuku (no PC), or with root. Steps are in the README. Limitations (being upfront) - Private DNS is a system-wide Android setting, so AppDNS switches it when the foreground app changes. It is not true per-app isolation like a VPN-based tool. Background traffic from other apps uses whichever DNS is active at that moment. - This is a very early version. Some phones may see sluggishness. [Add specifics: when it happens, e.g. at app switch, in the UI, or on certain brands.] - Android 9+ only, and DoT only (no DoH).

If something lags, please tell me your phone model, Android version, and what you were doing. Happy to answer any questions.   submitted by   /u/Correct_Rock5297 [link]   [comments]
