See what's on your network, and how you know.
NetScope lists the devices it can observe on your Wi‑Fi, tests your connection, and watches your home or office while you're away. Every result says where it was measured and when. Nothing is guessed.
Free on iPhone and iPad. Works without an account; scans stay on your phone unless you turn on sync.
- Listening for answers…
Discover
Every device that answers, with the method that found it and how confident the match is.
How discovery worksDiagnose
Latency, DNS, ports, speed and a connection check that each name their method and target.
See the toolsMonitor
A small agent at home keeps watching when your phone leaves, and tells you when something changes.
How monitoring worksAn inventory built from what actually answered
Supported discovery methods run together: interface inspection, Bonjour, SSDP, a bounded TCP sweep and reverse DNS. A device appears when something on the network answers for it, and its record keeps the proof.
| Address | 192.168.4.40 |
| Found by | Bonjour _airplay._tcp, port 7000 |
| Identity key | Service instance name. Survives an address change. |
| Model | Apple TV 4K |
| Operating system | tvOS |
| MAC address | Not exposed by iOS. A home agent can see it. |
| Trust | Trusted, set by you |
Identity with receipts
Strong keys come first: Bonjour instance names and UPnP ids. Then a unique hostname. An address alone only carries identity for a short while, and never when another device has claimed it.
Unknown is not intruder
A device with no name is marked “Needs review”. You decide whether it's trusted or ignored, and that decision follows the device.
Partial scans say so
If a method couldn't run on your device, the scan is marked partial and names the method, so an empty list never looks like an empty network.
Tools that name their method
Each test records its target, where it ran, how it measured and when. If a method isn't available on your device, the tool says so and offers the nearest honest alternative.
Latency
iOS apps can't send ICMP ping, so NetScope times a TCP handshake instead and says so. Min, median and max over your chosen number of attempts.
Port check
A refused connection proves a host is up. A timeout proves nothing. The result shows each outcome separately rather than collapsing them into “closed”.
DNS lookup
Query the system resolver or one you name. The answer records which resolver replied and how long it took.
Internet speed
Download and upload with the warm‑up excluded, data use shown before a cellular test, and the measurement endpoint named in the result.
Connection check
Four checks combined into cautious findings such as “possible DNS problem”, each backed by the observation that produced it.
Camera finder
Flags likely cameras from RTSP and ONVIF evidence with a confidence level you can correct. It never opens a video stream.
Security findings
Legacy services, router management pages and unreviewed devices. There is no single score, because a score would turn missing evidence into reassurance.
Keep watching after your phone leaves
A phone can't monitor a network it isn't on. A small agent on a device that stays at home can. Pair it with a single‑use code from the app; it sweeps every minute, reports every 30 seconds, and keeps recording through internet outages.
Alerts you tune
New device seen, a chosen device not seen for a while, repeated slow speed tests, a new security finding, or an unreachable agent.
Two timestamps on every event
Observations recorded during an outage arrive later with their original time intact, so the timeline stays truthful.
Health without guessing
That means the agent is unreachable. It might be the agent, its host, or the link. NetScope reports the fact, not a cause.
Things NetScope will not tell you
Network tools earn trust by being precise about their limits. These are written into the product, not just this page.
Your network is secure.Here are the findings, with their evidence.A service reachable from inside your network hasn't been proven reachable from the internet. An empty findings list is not a guarantee.
Device offline.Device not observed since 21:05.A sleeping phone and a missing phone look identical to a scanner. You get the last sighting and make the call.
Samsung TV, owned by Ana.Vendor and model are estimates; owner is whatever you typed.A hardware prefix names a registrant, not a product or a person.
Scan complete, 100%.Four of five methods ran. SSDP was unavailable.Progress reflects the methods that actually ran on your device.
Your internet is down.The home agent is unreachable.A missed heartbeat has several possible causes. NetScope doesn't pick one for you.

What works where
Phones and agents see different things, and platform rules change. The app shows this same table live, based on your device, permissions and network.
| Capability | iPhone and iPad | Home agent | Why |
|---|---|---|---|
| Bonjour discovery | Yes | Yes | Declared service types only on iOS |
| SSDP and UPnP discovery | With entitlement | Yes | iOS needs Apple's multicast entitlement |
| TCP reachability sweep | Yes | Yes | Bounded; a refusal counts as reachable |
| Other devices' MAC addresses | Not exposed | Yes | From the kernel's neighbor table |
| Wi‑Fi network name | With location access | Yes | iOS ties the name to location permission |
| Continuous monitoring | Foreground only | Every 60 seconds | Phones can't scan while asleep |
| ICMP ping and traceroute | Not supported | Planned | TCP latency offered instead |
| Block or pause a device | Router integration | Router integration | Only with a supported router; never by spoofing |
Anything NetScope can't do on your device is labelled in the app as not supported here, permission required, agent required, or router integration required.

Plan limits are enforced by the service and shown as plan limits, never dressed up as missing permissions. Prices are announced at launch.

Before you scan
Does NetScope send my network data anywhere?
Not unless you turn on sync. Scans run on your phone and stay there. If you create an account and enable sync, you choose when to upload saved scans, and you can delete your account and its cloud data at any time.
Why can't it show MAC addresses or my Wi‑Fi name?
iOS doesn't expose other devices' MAC addresses to apps, and it only reveals the Wi‑Fi name to apps with location access. NetScope shows both as unavailable with the reason. A home agent on Linux can see MAC addresses through the kernel's neighbor table.
Will it find every device on my network?
It finds devices that answer. A device that drops every probe, sits on another VLAN, or is asleep won't appear in that scan, and the scan's coverage says exactly which methods ran. The agent's neighbor table catches more than a phone can.
Can it block or pause a device?
Only through a supported router integration that can enforce and verify the change, which is planned. NetScope never interferes with traffic by ARP spoofing or Wi‑Fi deauthentication.
What do I need for monitoring?
A device that stays at the location, such as a Raspberry Pi, a NAS or a spare computer, running the NetScope agent on Linux. Pairing uses a single‑use code from the app. The agent only makes outbound connections, so no router changes are needed.
Where is the security score?
There isn't one. NetScope lists findings with severity, evidence, coverage and a recommended action. A score would turn a lack of evidence into reassurance, so we don't ship one.
