- Export Markdown Diagnostics: Copy structured diagnostic logs with one tap.
- Multi-Protocol Ping: ICMP (native), TCP, HTTP, and UDP modes with a live latency chart to visualize jitter.
- DNS Lookup: Query A/AAAA/CNAME/MX/NS/TXT records directly against public resolvers.
- TCP Port Scanner: Scan common NAS and remote desktop ports in one tap.
- Ignore Proxy Probing: Bypass system proxy settings to detect real direct connection status.
