NetSweep is a personal Wi-Fi diagnostic for iPhone. It maps every device on your own home network as a living canvas, explains what they're running in plain language, and helps you keep your connection healthy — without a laptop, a terminal, or a free afternoon.
Smart plugs, cameras, consoles, that one mystery box blinking in the corner — your home network is full of devices quietly doing things. NetSweep gives them a place: a spatial map you pan and zoom, where your router sits at the center and anything worth a look gently stands out.
Every device is a node you can drag, tap, and zoom into. New arrivals stand out, familiar devices settle in, and the whole canvas breathes with your network.
Check which services your own devices are running — your NAS, your printer, your Pi — with results explained in plain language, not port numbers.
An informational guide, not an alarm bell. Notes draw on public NIST NVD data to explain what a service is and whether it deserves a second look on your network.
See exactly what changed between two scans — devices that joined, left, or started advertising something new. Great for before-and-after router tweaks.
Latency, jitter, and throughput estimates with history and trends over time, plus exactly what the public internet sees about your connection.
Export any scan as a clean PDF or JSON — handy for your own records, a note to your ISP, or just tracking your network over time.
The home canvas is a customizable layout of tools — the same nine you'll find in the app, each doing one job well.
NetSweep is a diagnostic for the network you own, and that boundary isn't a disclaimer buried in a settings page. It's enforced three ways:
Every diagnostic target is validated against your own subnet on your active interface before a single connection is made. Anything outside it is refused at the engine level — no UI setting can bypass it.
Before the first scan, the app asks you to confirm you're the owner or authorized administrator of the network. The start button stays locked until you do.
Service Diagnostics shows a "Your network only" panel right above the input. Type an outside host and you get a clear explanation, not a scan.
No accounts. No analytics. No ads. Your scans never leave your phone. The only outbound requests are optional lookups — and they send a query, never your data.
NetSweep is a showcase of full-stack iOS craft: a custom SwiftUI spatial canvas with UIKit-backed gestures, a concurrent on-device diagnostic engine with hard local-network scope enforcement, SwiftData persistence, Swift Charts trends, scan-diff comparison, live NIST NVD integration, PDF generation, and accessibility from Dynamic Type to Reduce Motion.
