Use Cases

One network. Yours.
A lot to understand.

NetSweep does one thing: it helps you understand and look after the network you own. Here's how different people put it to work at home.

For smart-home owners

Finally know what's actually on your Wi-Fi.

Smart plugs, cameras, doorbells, the TV, the printer, that one mystery device — see them all on a living map, in plain language. When something new joins your network, you'll know.

  • A spatial map of every device on your home network, with hostname and vendor guess
  • "Devices worth a look" surfaces the handful that deserve attention — no alarm bells
  • Security Notes explain what a service is and why it matters, drawing on public NIST data
  • Optional alerts when a previously-unseen device joins your Wi-Fi

For developers & home-labbers

Check your own gear from the couch.

The Pi in the closet, the NAS under the desk, the dev server you just spun up — confirm what your own machines are serving, verify a local TLS certificate, and do subnet math without opening a laptop.

  • Service Diagnostics against your own devices — what's listening, explained clearly
  • TLS inspection for services on your network: certificate chain, expiry, handshake timing
  • Bonjour discovery to see what your devices are advertising to the house
  • DNS lookups and subnet calculators built in with Net Utils

For the household Wi-Fi fixer

"The internet is slow" — now you can actually answer.

When the connection feels off, get real numbers: latency, jitter, throughput, and what the internet sees from your side. Change a setting on the router, re-run, and compare scans to see exactly what it changed.

  • Connection telemetry with history and trends, so you can tell a blip from a pattern
  • Compare any two scans — devices and services that appeared, vanished, or changed
  • Gateway and public-connection info in one place when you call your ISP
  • Exportable PDF / JSON reports for your own records

Honest by design

What it does, what it refuses, and what iOS won't allow.

✓ What NetSweep does

  • Standard TCP-connect checks within iOS's sandbox — no private APIs
  • Bonjour / mDNS discovery of services your devices advertise
  • TLS, DNS, and connection-quality tooling for your own gear
  • Informational Security Notes backed by public NIST NVD data

⊘ What it refuses, on purpose

  • Any target outside your own subnet — refused at the engine level
  • Public IP addresses and internet hostnames as diagnostic targets
  • Running before you confirm the network is yours to look after
  • Exploit guidance of any kind — notes inform, they never instruct

✕ What iOS restricts

  • Reading other devices' MAC addresses (privacy-walled)
  • Raw sockets, ICMP ping, or ARP sweeps
  • Continuous background monitoring (only opportunistic checks)
  • Local-network access over cellular — there's no LAN there

NetSweep is a diagnostic for the network you own or administer. The boundary is enforced in code, confirmed by you at first launch, and visible in the app every time you use it — and the app never claims a capability iOS doesn't allow.

Built to be opened, not configured.

No setup, no agents, no dashboards to maintain. Just open it on your own Wi-Fi and look around.
