New — Certificate Expiry Tracker Add any domain and NetSleuth fetches its real SSL certificate and tracks days until expiry. Color-coded warnings at 30 and 14 days. Domains persist between sessions. Tap any entry to re-check. Swipe to remove. Enable notifications to get alerted when certs are expiring soon. New — Copy on Tap Long press any result in Ping, Traceroute, or DNS Lookup to copy it to your clipboard instantly. New — Subnet Calculator Enter any IP and CIDR prefix to instantly calculate network address, broadcast, first/last host, subnet mask, wildcard, usable host count, IP class, and binary mask. Built-in subnet splitter breaks any network into 2, 4, 8, or 16 subnets. New — LAN Scanner Discovers active devices on your local WiFi network. Shows IP, hostname, response time, and flags your device and gateway. New — TLS Inspector Tests TLS 1.2 and 1.3 support, shows cipher suites, certificate details, HSTS status, HTTP/2 support, and gives your server an overall grade from A+ to F. Speed Test — Rebuilt Completely redesigned to match Cloudflare's methodology. Uses multiple block sizes (100KB to 25MB) run multiple times each, with 90th percentile results — measuring what your connection typically delivers, not just its peak. Shows per-size breakdown, bufferbloat grade, loaded latency, and packet loss. WiFi Info — Rebuilt Now shows real connection data including connection type, IPv4/IPv6 support, Low Data Mode status, expensive connection flag, local IPv4 and IPv6 addresses, and WiFi security type — all 100% real data, nothing estimated. Signal strength (dBm) has been removed as Apple restricts access to this data from App Store apps.

New — MTR (My Traceroute) Combines ping and traceroute into one continuous live view. Discovers every hop to your destination then probes each one every second, showing packet loss percentage, last, average, and best latency per hop — just like the classic MTR tool.

Huge thanks to Matt for the ideas that shaped this update! New — HTTP Headers Inspector Enter any URL and instantly see the full HTTP response: status code, all response headers, redirect chain, and time to first byte. Headers are expandable and selectable. Perfect for debugging APIs and web servers. New — Port Checker Presets Tap a category to instantly scan relevant ports — Web, Email, Database, Remote Access, or Gaming. No more typing port numbers manually. New — Share Results Ping, Traceroute, Port Checker, and Speed Test results can now be shared or copied via the system share sheet. WiFi Info — Signal Strength Fixed Signal strength in dBm was stuck at -90 dBm due to a mapping bug. Now correctly mapped across the full range, with a realistic fallback when iOS returns a zero value. WiFi Info — Auto Refresh New refresh interval picker (1s / 5s / 10s) lets you control how often signal strength and network info updates. Speed Test — More Accurate Rebuilt to use 4 parallel download connections and 3 parallel upload connections with wall-clock timing — the same approach real speed tests use to fully saturate your connection. Test duration extended to 10 seconds per phase.

Matt to the rescue again * Speed Test — Completely Rebuilt Now measures your connection the way Cloudflare does. Tests run in five phases: latency & jitter, download, loaded latency, upload, and packet loss. Results include a Bufferbloat Grade (A–F) showing how your connection holds up under real load — something basic speed tests miss entirely. * WiFi Info — Signal Strength Fixed Signal strength in dBm, SSID, BSSID and channel now display correctly after resolving a compatibility issue with newer versions of iOS. * Traceroute — Real Hostnames Each hop now performs a live reverse DNS lookup, showing actual router and infrastructure hostnames instead of placeholder text.

Huge thanks to Matt for the feature ideas that shaped this update! New Tools: DNS Propagation Checker — See if your domain has propagated across 10 major DNS servers worldwide including Google, Cloudflare, Quad9, AdGuard, OpenDNS and more. Live progress bar, per-server latency, and resolved IP all in one view. DNS over HTTPS (DoH) Checker — Find out if your device is using encrypted DNS. Tests 6 major DoH providers (Cloudflare, Google, Quad9, AdGuard, NextDNS, OpenDNS) and estimates whether your traffic is protected with DNS-over-HTTPS. Upgraded Tools: Ping — Added continuous ping mode. Enable it to ping forever with a live scrolling line graph showing the last 60 results, color-coded by latency. Timeouts appear as red dots on the graph. Traceroute — Completely reworked. Each hop now performs real TCP probes to actual internet infrastructure with live reverse DNS lookups, showing real hostnames at each hop instead of placeholders. Speed Test — Rebuilt from the ground up for accuracy. The test now runs for ~16 seconds using 25MB download chunks to properly saturate your connection. Results use a trimmed mean to filter outliers, and sparkline charts show per-sample variation so you can see consistency. WiFi Info — Now shows signal strength in dBm, signal quality rating (Excellent / Good / Fair / Poor), visual bar indicator, SSID, BSSID, and channel with 2.4 GHz / 5 GHz detection. Tap "Enable Signal Info" to grant location access — no automatic prompts.
