You can probably name every phone and computer in your home without thinking twice.
But what about the TV, printer, cameras, smart speakers, NAS, and that old tablet you occasionally pull out of a drawer?
As more devices get connected, your home network becomes a small collection of systems quietly working in the background. Then one day, you want to identify an unfamiliar device or troubleshoot a connection—and realize you could use a clearer picture of what’s there.
WiFi Health Check brings device discovery, network diagnostics, walk tests, and stability testing to iPhone and iPad, so you can explore your network directly from your mobile device.
01 | Start by Seeing Who’s on Your Network
Running a LAN scan and watching devices appear in the list is one of the most direct ways to get to know your network.
Phones, computers, printers, cameras, network equipment—devices scattered across different rooms and management interfaces can now be viewed in one place. Device category counts also make it easier to see how your network is made up.
If you have a NAS, virtualization hosts, or smart home devices, this inventory is especially useful. After connecting a new device, you can check whether it has been discovered and view its IP address and identification details.
02 | What Exactly Is That Unfamiliar Device?
The entries that make you pause are often the ones with names you don’t recognize: an unfamiliar hostname, an IP address, or a record that shows only a manufacturer.
WiFi Health Check combines multiple clues to help identify devices, including their manufacturer, device category, model, and discoverable services.
Multicast Discovery is particularly useful here. Devices can announce information through local discovery protocols, and the app combines those details with other probe results to build a more informative device list.
For example, mDNS / Bonjour, SSDP, and WS-Discovery can provide useful clues for identifying Apple devices, printers, media devices, and cameras.
Once you’ve identified a device, you can give it a memorable alias. The next time you see “Office Printer” or “Living Room TV,” you won’t have to work out what it is all over again.
03 | What Has Changed Since the Last Scan?
You’ve installed a new camera, replaced a phone, or rearranged your network equipment. What’s different from your previous scan?
Scan history and device change comparisons let you review results from different points in time, see newly discovered devices, and check which devices were not found in the current scan.
For a home network with plenty of devices—or a small studio—this saves you from repeatedly scrolling through lists and manually comparing addresses. Giving important devices recognizable aliases makes the changes even easier to follow.
Your network inventory now has a timeline: you can inspect the current results and look back at earlier records.
04 | Same Wi-Fi, Different Room—Why Does It Feel Different?
Video streams smoothly in the living room but occasionally stutters in the office. Meetings work well at your desk, yet moving to another room makes the connection feel less dependable.
Start with a network diagnostic to check the current connection. Then use a walk test to test the same target from different locations and compare the results.
You can take measurements in the living room, office, and bedroom, then use those results alongside your everyday needs to decide which location works best for video calls, remote work, or accessing your NAS.
Instead of relying only on “the connection feels unstable here,” you have test records you can revisit when making changes.
05 | It Connects Now. Will It Stay Stable?
A webpage loading successfully tells you that it’s reachable at that moment. For a long video call, a remote connection, or access to services at home, you may also want to know how the connection behaves over time.
Stability testing repeatedly checks a chosen target and tracks metrics such as connection success rate, latency, and jitter.
You can test a service you use regularly or specify an IP address and port to see whether connections keep succeeding and whether latency fluctuates noticeably.
Run a test before and after a network adjustment, and the difference becomes easier to see.
From Knowing Your Devices to Understanding Your Connection
A device inventory helps you get to know your local network. A diagnostic check, a set of walk test results, and a stability test help you understand how it performs in everyday use.
WiFi Health Check brings these tools together on iPhone and iPad, so you can discover devices, explore identification details, review network changes, and check connection performance.
