## What is NetDebug Toolkit?

NetDebug Toolkit is the all-in-one network diagnostics suite for developers, sysadmins, IT teams, and power users. 

19 pro-grade tools on iPhone, iPad, and Apple TV. Fast. Focused. No account. No tracking.

Diagnose connectivity, DNS, routing, ports, certificates, throughput, and local-network services from one clean interface:

NETWORK CORE
• Ping : ICMP or HTTP HEAD reachability with timing and packet-loss stats
• Traceroute : hop-by-hop route inspection
• HTTP(S) Check : status, redirect chain, headers, TLS summary
• Speed/Latency Baseline : download/upload presets from 1 MB to 64 MB
• iperf3 Client : TCP throughput against an external iperf3 server (upload or download)
• Public IP + Geo / ASN / ISP : current WAN IP with carrier and location detail

DNS & DOMAIN
• DNS Lookup : forward (host to A/AAAA) and Reverse DNS (IP to PTR), auto-detected from input
• DNS Record Explorer : A, AAAA, CNAME, MX, TXT, NS, SRV via DNS-over-HTTPS (custom resolver supported)
• Whois : RDAP or IANA WHOIS mode, with chained referrals

SECURITY & TLS
• TLS Certificate Inspector : full chain, validity, SANs, signature algorithm, weak-cert signals
• Subnet Calculator : IPv4 and IPv6, usable host range, broadcast, gateway hints

PORTS & CONNECTIVITY
• Port Scan : custom ports or ranges
• TCP/UDP Connect : per-port reachability with built-in UDP profiles (DNS, NTP, SNMP, SIP, RADIUS, TFTP, memcached)
• NTP Time Check : clock offset vs. any NTP server with delay, stratum, and leap details
• External Port Check : "can the internet reach me?" TCP port-forwarding test from an outside server (open/closed/filtered)
• Run History & Trends : every run is saved on-device with charts of latency, speed, and more over time (free; longer retention with a purchase)

LOCAL NETWORK
• LAN Scan : fast or deep subnet host discovery
• mDNS / Bonjour Browser : AirPlay, HomeKit, Matter, printers, SMB, SSH, and more
• UPnP / NAT-PMP Discovery : router gateway port-mapping introspection
• Wake-on-LAN Sender : send magic packets to wake compatible devices

POWER-USER WORKFLOW
• Saved Hosts : store frequently used IPs, hostnames, and MAC addresses with per-host tool defaults
• My Automation : chain multiple tools into one-tap workflows with a combined PDF, PNG, or text run report
• Export & Import : portable JSON files for automations and saved hosts (iOS share sheet, tvOS QR-code download)
• Universal Links & Deeplinks : open any tool from a URL with pre-filled inputs, auto-run, and auto-export, e.g. https://netdebug.developerinsider.co/open/ping?target=1.1.1.1&export=pdf
• Copy Deeplink : every tool and saved automation can copy its own shareable Universal Link
• Built-in tool docs : quick-reference markdown for every tool

APPLE TV / tvOS
• Full feature parity : every tool, Saved Hosts, My Automation, and all three in-app purchases ship on Apple TV
• LAN-only QR-code export : Apple TV serves run reports and JSON exports over a one-shot HTTP server; scan the QR with your phone to download

LOCALIZED IN 21 LANGUAGES
English, Arabic, Bengali, Chinese (Simplified), Dutch, French, German, Hindi, Hinglish, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Spanish, Thai, Turkish, Ukrainian, Vietnamese.

OPTIONAL IN-APP PURCHASES

## Version history (last 5 releases)

### 2.1 — 2026-08-08

New Tools
• NTP Time Check : run an SNTP query against any NTP server to read your device's clock offset and round-trip delay, plus stratum, leap indicator, reference ID, and Kiss-of-Death detection.
• External Port Check : see whether the internet can actually reach you. Our server connects back to a chosen port on your public IP and reports open, closed, or filtered, ideal for verifying port forwarding and inbound reachability. It complements Port Scan, which probes outbound from your device.

Run History and Trends
• Run History: every manual run and automation step is now saved on your device with its tool, target, time, duration, status, full output, and metrics, so you can look back instead of testing again from memory.
• Trends: line charts turn those saved runs into a picture over time: download and upload Mbps, latency, jitter, packet loss, NTP clock offset, and HTTP response time, filterable by target and time range.
• Re-run, export, or delete any past run: reach history from a Quick Access row, or per host from the Host Tools screen.
