NetScanPro: Network Scanner

NetScanPro turns your iPhone into a professional-grade Wi-Fi network scanner. Discover what's on your network, identify what each device actually is, see which services are exposed, and understand what might be at risk — with all scanning and identification happening on your device.

FEATURES

Device Discovery

• Finds devices on your local Wi-Fi network using four discovery methods working in parallel: TCP probing, Bonjour/mDNS, SSDP/UPnP, and ICMP ping
• Shows IP addresses, IPv6 addresses, hostnames, and device categories
• Works with Macs, PCs, smart TVs, printers, speakers, Fire TVs, Apple TVs, routers, smart-home and Matter devices, and more

Device Identification

• Identifies devices from Bonjour records, UPnP announcements, open-port patterns, and — for devices that broadcast one, such as AirPlay and Chromecast hardware — MAC vendor prefixes matched against the full IEEE manufacturer database, bundled offline
• Reads the Bonjour service types printers, speakers, streaming devices and smart-home hubs use to announce themselves
• Every identification carries a confidence level, so you can tell a confirmed match from a best guess
• The device you're scanning from identifies itself
• Devices that share nothing identifiable stay unlabeled rather than mislabeled
• All identification happens on-device with no cloud lookup

Port Scanning with Plain-Language Descriptions (Pro)

• Tap any device to scan 27 common TCP ports
• Identifies HTTP, HTTPS, SSH, FTP, SMB, IPP, RDP, VNC, and more
• Tap any port to learn what it actually does — no networking degree required
• Security guidance for sensitive ports explains real-world risks like WannaCry, credential exposure, and exposed cameras and printers, with severity tiers so you know what needs attention
• See exactly which services are running on each device
• Devices with a web port open get a one-tap link into Safari — the fastest way to identify something that won't tell you its name

Network Security Summary (Pro)

• Scan every device on your network at once and see all your security findings in one place
• Findings grouped by service and ordered worst-first, so you can spot patterns across your whole network at a glance
• Tap any finding to see exactly which devices are affected
• Color-coded severity separates real risks from what's just worth knowing
• See every device with a web port open in one place, with one tap to each

Network-Aware Scanning

• Each Wi-Fi network keeps its own separate device list
• Switch between networks (home, work, anywhere) with a tap
• Per-network scan history, device renaming, and PDF reports
• Rename a device and the name sticks, even after your router hands its address to something else. When NetScanPro can't tell whether a device moved, it asks instead of guessing — and the answer can be undone for two weeks
• Create networks manually and pin a scan to one, so two sites that look identical (same subnet, same gateway) stay separate
• Move devices between networks to reorganize your catalog

Privacy First

• Face ID or passcode locks the app
• All scanning happens on-device — nothing is transmitted to servers
• No accounts, no analytics, no tracking SDKs
• Your scan history stays on your phone

Freemium

• Free: unlimited device discovery, 3 network scans per day
• Pro ($6.99 one-time): unlimited scans + port scanning on every device + network security summary + PDF report export + device renaming. No subscriptions.

Built for home network administrators, IT professionals, security-conscious users, and anyone curious about what's on their Wi-Fi.

The in-app help screen explains how device discovery works and which devices may not appear (some IoT and privacy-mode phones don't expose themselves to any iOS scanner).

Note: NetScanPro is designed for use on networks you own, administer, or have explicit permission to inspect.
