Linkalyst vs Throughput

Ping with a live latency chart, query encrypted DNS (DoH and DoT), check TCP ports, see where an HTTPS request spends its time and trace every hop, on iPhone and iPad. Test results are saved as reports you can search and share. EVERYDAY CHECKS • Internet Speed Test: download and upload in one tap • Popular Services: how fast popular sites and services connect, ordered for your region • Discover: your gateway, Bonjour services and My Devices in one place • This Device: model, battery, storage and how this device connects • Share a Card: share a speed test, Popular Services or latency result as an image; five more styles with Plus MEASURE THE CONNECTION • Chart Ping (ICMP) probes live; up to six targets in one run and UDP probes with Plus • Typical latency (P50), slower requests (P95, P99), variation, timeout rate and longest timeout streak • Tap the chart to inspect a request and add notes as you test; timeouts are marked, never plotted as latency • Check a TCP port once or up to 50 times in a row SEE WHERE EVERY MILLISECOND GOES • Website Check sends five HEAD or GET requests in a row and can follow redirects hop by hop • Times DNS, TCP, TLS and time to first byte • Shows the HTTP protocol, TLS version, cipher suite and certificate chain, with expiry dates and SHA-256 fingerprints COMPARE DNS RESULTS • Query system DNS or choose UDP, TCP, DNS over HTTPS (DoH) or DNS over TLS (DoT) • Compare system DNS with up to four resolvers, each on its own protocol: fastest this round, record differences, response codes and failures (Plus) • Presets for Cloudflare, Google and DNSPod, or a custom endpoint • A, AAAA, CNAME, MX, TXT, NS, SOA and PTR records, with TTLs • DoH and DoT apply to queries in Linkalyst; they don't change your device's DNS settings SCAN PORTS AND ORGANIZE DEVICES • Batch Scan in Port Check takes IPv4 lists or CIDR and known IPv6 addresses, with port presets or your own ranges: up to 256 addresses and 4,096 address/port pairs per run (Plus) • Discover scans your network and lists devices that answer, with names, services and open ports; on iOS 27 also hardware addresses and makers (Plus) • Keep targets, notes and related reports in My Devices, optionally grouped by network ROUTES, SPEED AND ADDRESSES • Route Trace for IPv4 and IPv6: up to 30 hops, 1 to 3 probes per hop, optional hop hostname lookup • See this device's addresses and gateway; turn on IP Lookup in Settings for your public IP, region, network organization and ASN (via FreeIPAPI) • Download Test for a URL you choose, up to 64 MiB or 10 seconds • Throughput Test for upload or download to a free test peer you run on your own computer • Offline IPv4/IPv6 Subnet Calculator KEEP THE RESULTS • Search, star and tag reports; share them as JSON, or request-level data as CSV (one export free, then Plus) • Compare two runs with latency curves overlaid; repeated port checks, website checks, download and throughput tests and route traces are paired by target (Plus) • Optional iCloud Drive report sync, off by default (Plus) BUILT FOR IPHONE AND IPAD • Follow a running test on the Lock Screen and, on supported iPhones, in the Dynamic Island, where you can also stop it • On iPad, open the tools or a single report in its own window Use network tests only on systems you own or have permission to test. UDP latency and Throughput Test require a compatible test peer; instructions are linked in the app. Linkalyst is free to download, and its everyday tools are free. Items marked (Plus) need Linkalyst Plus, a one-time purchase that also removes all ads and supports Family Sharing.

Test network throughput between your device and an iPerf3 server. View upload and download speeds with smooth gauges and live charts, including average speed and a sustained one-second peak. FREE CLIENT FEATURES • Upload, download, or both in sequence • TCP and UDP, configurable duration, parallel streams, port, and UDP bitrate • Local server discovery with hostnames when available • Public server browser on iPhone, iPad, Mac, and Apple TV, with cached listings from iperf3serverlist.net and port-range retry options • Continuous testing with a 10-second pause between runs • Background client testing on iPhone and iPad while iOS allows execution • Live Activity with speed, direction, progress, and a chart • Apple TV remote controls and a layout designed for the TV • Native Mac app with a live menu bar gauge SERVER & HISTORY — OPTIONAL ONE-TIME PURCHASE Unlock server mode and saved history on iPhone, iPad, Mac, and Apple TV, plus saved history on Apple Watch, using the same Apple Account. • Run an iPerf3 server from the Server tab on iPhone, iPad, Mac, or Apple TV • See incoming test gauges and charts, and review completed server results during the current app session • Save completed client tests, inspect charts and results, and reuse test settings • Export saved results as JSON on iPhone and iPad GETTING STARTED Run iperf3 -s on another computer, then enter its hostname or IP address in the app. Compatible local servers can also be discovered automatically, or choose Configure > Public servers to browse internet servers. Public server availability varies. An iPerf3 server is required for native client tests; iperf2 and authenticated servers are not supported. UDP measures delivery at your chosen target bitrate. Each direction begins with a one-second warm-up before measurements appear. Server mode runs while the Server tab is open. iPhone, iPad, and Apple TV servers require the foreground; the Mac server can keep running while hidden. Background client execution is controlled by iOS and can be stopped by the system. Apple TV client tests require the app to remain in the foreground. APPLE WATCH Run HTTP upload and download tests against this app’s enhanced server mode, with charts, queue positions, latency, and optional saved history. Open the iPhone app to share discovered servers or its own running server. Tap a server on Watch to run a 15-second upload and download test with four connections. Both gauges and charts fit on one screen. watchOS may route traffic through the paired iPhone; results may not represent a direct Watch Wi-Fi connection. HTTP measures TCP payload throughput and does not measure UDP loss or UDP jitter. Keep the Watch app open during tests. No app account, advertising, or analytics. Test traffic goes directly to your selected server. History stays on each device and does not sync; Apple TV may purge cached charts. Purchases are handled by Apple.
