## What is NetSleuth?

NetSleuth is a powerful network diagnostic toolkit for iPhone and iPad. Whether you're a developer, IT professional, or just someone who wants to understand what's happening on their network, NetSleuth gives you professional-grade tools in one clean, fast app.

* Speed Test
Measures your connection the way it should be measured. Tests download, upload, latency, jitter, loaded latency, and packet loss — then gives you a Bufferbloat Grade (A–F) showing how your connection performs under real load. Powered by Cloudflare.

* Ping
Ping any host with a single burst or continuous mode. Watch latency in real time on a live scrolling graph with color-coded results and timeout detection.

* Traceroute
Trace the full path to any host with live reverse DNS lookups showing real router and infrastructure hostnames at every hop.

* DNS Lookup
Query A, AAAA, MX, TXT, CNAME, and NS records for any domain.

* DNS Propagation
Check if your domain has propagated across 10 major DNS servers worldwide including Google, Cloudflare, Quad9, and AdGuard.

* DNS over HTTPS (DoH)
Test whether your device is using encrypted DNS. Checks 6 major DoH providers and estimates your protection level.

* Port Checker
Scan common ports on any host to see what's open or closed.

* WHOIS
Look up domain registration and ownership details instantly.

* SSL Inspector
Inspect SSL/TLS certificates — view issuer, validity dates, and days until expiry.

* WiFi Info
See your local IP, external IP, subnet, gateway, and DNS. Enable location permission to reveal signal strength in dBm, SSID, BSSID, and channel with 2.4/5 GHz detection.

* IP Info
Geolocate any IP address with a map view, ISP, timezone, region, and coordinates.

No ads. No account required. No data collected.

## Frequently asked questions about NetSleuth

### What is NetSleuth?

NetSleuth is a powerful network diagnostic toolkit for iPhone and iPad. It provides professional-grade tools like speed tests, ping, traceroute, and DNS lookups to help users understand their network performance and security.

### Does NetSleuth have ads?

No, NetSleuth is ad-free. The app explicitly states 'No ads. No account required. No data collected.'

### What network tests can I perform with NetSleuth?

NetSleuth offers a comprehensive suite of tests including Speed Test (download, upload, latency, jitter, packet loss, Bufferbloat Grade), Ping, Traceroute, DNS Lookup (various record types), DNS Propagation, DNS over HTTPS (DoH) testing, Port Checker, WHOIS, SSL Inspector, WiFi Info, and IP Info.

### Is NetSleuth available on Android?

Based on the provided information, NetSleuth is designed for iPhone and iPad, indicating it is an iOS-exclusive application.

### How does NetSleuth's speed test work?

The speed test measures download, upload, latency, jitter, loaded latency, and packet loss. It then provides a Bufferbloat Grade (A–F) to show how your connection performs under real load, powered by Cloudflare.

### What information does NetSleuth provide about my WiFi connection?

With location permission enabled, NetSleuth can display your local IP, external IP, subnet, gateway, DNS, signal strength in dBm, SSID, BSSID, channel, and whether it's a 2.4 GHz or 5 GHz connection.

### How often is NetSleuth updated?

The latest version of NetSleuth is 1.6, and it was last updated on May 1, 2026. This suggests a relatively active development cycle.

### What is the age rating for NetSleuth?

NetSleuth has an age rating of 4+, making it suitable for a wide range of users, including younger individuals interested in network diagnostics.

## Version history (last 4 releases)

### 1.6 — 2026-05-01

* Added a new Home dashboard for faster access to common diagnostics
* Added Saved Targets for frequently checked domains, hosts, and IP addresses
* Added Recent Targets so you can quickly rerun checks
* Added a Full Diagnostic workflow for running multiple checks on one target
* Added Reports and History for reviewing previous diagnostic results
* Added a new Settings area with local data controls
* Improved tool organization and navigation
* Improved certificate tracking visibility
* Added clearer wording around TCP-based reachability checks on iOS
* Improved sharing, copying, and export behavior across diagnostic results
* Fixed Swift 6 compatibility issues in Speed Test
* Fixed a certificate tracker crash caused by overlapping timeout and certificate callbacks
* Removed an iOS 17-only empty state view for better compatibility with older deployment targets
* General UI polish, reliability improvements, and bug fixes

### 1.2 — 2026-03-29

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.

### 1.1 — 2026-03-27

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.
