  • Free
  • Built for iPhone
  • English + Simplified Chinese
  • Core diagnostics run natively

Diagnose the full path, not just one symptom

Start with reachability, inspect every hop, verify DNS and certificates, test the local LAN, then export the result. The tools share one compact, dark interface designed for field work rather than a collection of unrelated web views.

Reachability and paths

  • Ping — live graph, loss, jitter, stability grade, and p50/p95/p99 latency
  • Traceroute — per-hop timing with a visual route map
  • MTR — continuously refreshed path loss and latency
  • Global Ping — probes from 10 worldwide cities via globalping.io

DNS, addressing, and security

  • DNS records through DoH or a custom resolver, plus DNS benchmarking
  • WHOIS / RDAP for domains, IP addresses, and ASNs
  • Offline IPv4 and IPv6 subnet calculator
  • TLS chain, expiry, SANs, protocol, and cipher inspection
  • IPv6 reachability and NAT64 / DNS64 diagnostics

Local network

  • Concurrent LAN discovery with device labels and custom names
  • Bonjour browser for HTTP, SSH, SMB, AirPlay, HomeKit, printers, and more
  • Network Watch notifications when a new device joins
  • Wake on LAN for saved devices

Performance and workflow

  • Speed test with loaded latency, jitter, loss, and bufferbloat grade
  • HTTP status, headers, redirects, and DNS/connect/TLS/TTFB waterfall
  • Concurrent TCP port scan with service identification
  • Share and export, public-IP home-screen widget, and “Ping a host” Siri shortcut

What version 1.0.1 adds

The current App Store release expands the original diagnostic set with DNS Lookup, DNS Benchmark, WHOIS / RDAP, Subnet Calculator, TLS Inspector, HTTP Request, and IPv6 Diagnostics. Ping, speed testing, LAN discovery, and traceroute also receive deeper measurements and clearer visual output.

Privacy and network access

Hosts, addresses, and results are not recorded in TelcoAIO analytics. Tools that need live Internet data necessarily contact the selected destination or named provider; local calculations stay on the device. Review the app privacy policy before use.

Requirements and support

  • iPhone with iOS 17.0 or later
  • English and Simplified Chinese interface
  • Internet access is required for remote lookups and distributed tests
