DNS Speed Tester — Find the Fastest DNS for Your Network

Slow browsing, high ping, or dropped connections? Your DNS provider might be the problem. DNS Speed Tester benchmarks and compares the latency, speed, and reliability of multiple DNS servers in real-time, right from your Android device.
Key Features:

Real-Time Latency Dashboard — Live interactive graphs as you ping multiple DNS providers simultaneously.
Multiple Query Protocols — Test over UDP, DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), or ICMP Ping.
Top Providers Pre-Loaded — Includes Google, Cloudflare, and curated categories: Privacy First, Security First, and Family/Ad-Blocking.
System DNS Detection — Automatically detects and benchmarks your current active DNS settings against the competition.
Fully Customizable — Add your own DNS providers, choose test domains, and adjust concurrency and timeout settings.
Export & Import — Backup and restore your custom DNS lists and configurations via JSON.
Light/Dark Mode — Automatic, native Android UI.

Whether you're a gamer chasing lower ping, a privacy advocate moving to DoH/DoT, or a network admin troubleshooting slow queries, DNS Speed Tester gives you the data to make the right call.
