iPerfman vs NetDebug Toolkit

iPerfman measures network performance between your device and a compatible iperf3 server. Run TCP or UDP tests on iPhone, iPad and Mac. The free version allows three tests per day; Pro unlocks unlimited tests and advanced controls. Measure and investigate: - Test upload, download or both directions, with separate results for each direction. - Follow throughput in live charts. View UDP jitter and packet loss, TCP retransmissions, and round-trip time when those measurements are available. - Save completed tests with their configuration and interval results, then rerun a test or review its history. - Choose an IPv4/IPv6 interface when running a server, or listen on all interfaces. Unlock Pro with a monthly or yearly subscription, or a one-time Lifetime purchase. Pro adds unlimited daily tests, advanced iperf3 parameters, comparison of saved results, and full report export. The yearly subscription includes a seven-day free trial for eligible customers. Existing Lifetime purchases remain valid. iPerfman uses iperf3 3.21 through IperfSwift. A compatible server or second device is required for a network test; this is not an internet speed-test service. The Apple TV app uses a separate interface and has a different feature set.

NetDebug Toolkit is the all-in-one network diagnostics suite for developers, sysadmins, IT teams, and power users. 20 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 • Path MTU Discovery : largest packet a route carries, black-hole detection, the constricting hop, and safe inner MTU for VPN 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.
