A map of your network: the router in the middle, every device around it.
Census lists the devices on your Wi‑Fi or Ethernet — name, model, maker, IP address, and when each one first showed up — in a single window. Anything your Mac or iPhone has never seen before gets a NEW badge. And when a device can't be identified, Census tells you why instead of printing “unknown”.
What you see
A map of the network, or a plain list grouped by kind — phones and tablets, computers, TVs and speakers, smart home accessories, and the ones that only left a trace.
For every device: its name, the model it reports, the maker of its hardware address, its IP, what it offers (web page for settings, file sharing, screen sharing, printing), and when it was first and last seen.
A badge on anything new, with the time it appeared. Mark a device as known (one-time unlock) and it stops counting as new.
Your own name for any device (one-time unlock). Names and history stay on your device.
A quiet re-check every 30 seconds, and a notification when something new joins (one-time unlock).
What it doesn't do
No account, no sign-in, nothing in the cloud. History and the names you give devices stay on your device.
Nothing is uploaded, ever. The hardware-maker table ships inside the app and is never fetched at runtime.
Free to download, with no ads and no cap on devices: the full list, the details and the reasons are free. A one-time purchase adds the quiet re-checks and notifications, your own names, marking devices you know, and CSV / JSON export, on Mac and iPhone. No subscription.
No Wi‑Fi signal or channel analysis — so Census never asks for your location.
Anything Census has never seen before gets a NEW badge, with the time it appeared.
Why a device can't be identified
This is the part other scanners leave blank. Census explains each case in plain words, and tells you how to check for yourself:
Private Wi‑Fi address — phones make up a random hardware address for every network they join. That's a privacy feature working as intended, not a fault.
The device doesn't answer name lookups, or doesn't advertise anything about itself.
Seen recently, quiet right now — a sleeping laptop, phone or smart plug looks exactly like this.
This network keeps devices apart — guest networks and hotel Wi‑Fi often do, and no app can look past that.
The same network as a list, grouped by kind.
On iPhone
Census is free on iPhone too, and one unlock covers both. It shows the same list, grouped by kind, with the same NEW badges and the same explanations. A few things differ. There is no map view, just the list. iOS doesn't give apps a device's hardware address, so the iPhone version can't show the maker; the Mac version can. And the iPhone checks when you open it (pull down to check again) instead of every 30 seconds in the background. It needs the Local Network permission, and nothing leaves the phone.
Honest limits
No app can find a device that is asleep, one that is set to ignore these checks, or anything hidden by client isolation on a guest network. Census says so when that is what happened, instead of quietly showing you a short list.
